  • Hand tools

    Make sure the size of the wrench matches the size of the nut/bolt.

    Do not use screwdrivers instead of chisels or crowbars.

    Make sure that the size and type of the screwdriver matches the size and type of the screw.

    Use the control pen as intended, do not use it as a general purpose screwdriver.

    Do not use products such as pliers, yankeski, T Allen as a hammer, and do not hit the handle and jaw parts.

    Do not cut hard steel wires with pliers or thin scissors.

    Do not use the hammer on materials harder than its own hardness and do not work with the corner parts of the hammer.

    Do not attach an extension arm to any handpiece to gain more force.

    Pay attention to the direction of rotation of the wrench, especially for wrenches and pipe wrenches. In such products, the movable jaw should not be loaded.

    Do not use pipe wrenches with worn threads.

    Use a pipe wrench suitable for the diameter of the material.

    Do not use socket wrenches with an air gun. Prefer sockets specially produced for air guns.

    Be careful not to wear out the ends of the circlip pliers.

    Be sure to use hand tools for their intended purpose.

    Do not apply chemical processes, sharpening and welding processes to hand tools. Do not modify the shape of the instruments.

    Do not use worn or faulty hand tools.

    When moving the wheeled repair cabinets from one place to another, make sure that the drawers are closed and that the cabinet is locked.

    During operation, make sure that all drawers of the wheeled repair cabinets are not open at the same time. Otherwise, the balance distribution of the cabinet will be disturbed and it may be overturned.

    After using hand tools, be sure to keep them clean and maintained.

    Be sure to use personal protection equipment suitable for your working conditions.


    With the continuous development of technology day by day, processes such as material shaping and assembly are carried out with the help of machines controlled by computers or control systems. However, when a prototype (first product) is desired to be made, hand and power tools will always be needed and these equipment will never be replaced by fully automatic machines. For this reason, knowing hand and power tools and knowing safe usage techniques is always an inevitable reality for people dealing with technology.
    When cutting wire with cutting-edged tools such as picks and pliers, the handle or jaw parts should not be hit with a hammer, and the tool should not be used as a hammer. As stated in the standards, these tools are produced from alloy steels by hardening in heat treatments in order to increase their resistance to wear. Because they are hard, they can break when exposed to impact and cause work accidents. The cutting edges of such tools have a hardness of 57-58 HRC and should be used in hardnesses below 50 HRC. These are materials such as copper, aluminum and construction wire. If it is used to cut hard steel wires, the healthy life of the tool will expire in a shorter time. It is more convenient to use wire cutters to cut hard steel wires.
    Of the two materials, the harder one will scratch, cut, or deform the softer one under all circumstances. This is especially true for hammers. The base of the hammers is hardened by induction and is 52-54 HRC. In this direction, if the hammer is used on materials harder than its own hardness, it will be deformed. In addition, the edge, tip and corner parts of the hammer should not be exposed to impact. As the hammer is used, cork forms on its edges over time, and these cork must be cleaned by grinding in order not to break off during use and cause work accidents. Coolant should be used in order not to affect the hardness during grinding.
    There are a few points to consider when using the tools in the pipe wrench group, which are mostly used by plumbers. Before applying the load, the wrench should be adjusted with the help of the adjusting bolt until it fully grasps the fastener to be removed or tightened. When the load is applied, the mouth of the wrench must grasp the part from its widest surface so that it does not slide. When using such tools, we should work by pulling the key, not pushing it. In addition, working by attaching extension arms such as a pipe to the handle will shorten the healthy life of the key. A situation that will shorten the service life of the wrench is to work with tools such as hammers with impact. It is more convenient to lubricate and use rust remover to loosen the rusty, tight connection instead of pipe fitting or hammering.
    Fork, star and combination wrenches, which are among the most used hand tools, are produced in accordance with TSE and DIN norms regarding the amount of load they must withstand. If these values ​​specified in the standards are exceeded, there is a high probability that the handpiece will break down. One thing to note is that metric bolts should be used with a metric wrench, and an SAE bolt with an SAE (inch) wrench. SAE bolts with a metric wrench or metric bolts with an SAE wrench should not be used, even if the sizes are close to each other. Otherwise, the wrench will not be able to fully grasp the nut (or bolt) and will slide. As a result of sliding, the bolt or key will be deformed. When the bolt is damaged, it will also damage that key as it will slide even if it is worked with the appropriate key later on. The connection will become non-disconnectable. Therefore, if the nut-bolt to be tightened or removed before using the wrench is metric, it should be ensured that the wrench is metric.
    One of the most important points to be considered in the use of socket torx and allen wrenches is that impact loads should not be applied. As an uncontrolled load will be applied as in fork-star wrenches as a result of applying an impact load, the resistance value of the wrench can be exceeded. This makes the key unusable by breaking. If we give an example of such applications, using air or electric drills, working with a hammer while working with a T arm can be an example. As it can be understood, these wrenches are not suitable for use with machinery, they must be worked with a T-handle. While working with T arm, extension arm and hammer should not be used. In addition, before using the socket wrenches and allen wrenches, check the size of the wrench and bolt. After the key is in the slot, there should be no gap.
    When using the Allen group with a wrench, it is not appropriate to apply an excessive load by attaching pipes or extension arms. In addition, metric allen bolts must be used, and SAE (inch) allen bolts must be used for SAE (inch) bolts.
    When using a toad and armature wrench, the direction of turning the wrench is important, as the figure shows. In these wrenches, the upper jaw is more durable than the adjustment jaw. In other words, if possible, the adjustment jaw should not be loaded. The load should be on the upper jaw and the adjusting jaw should act as a support. This is correct usage. If the load is on the adjustment jaw and the upper jaw acts as a support, this is not a recommended use.
    When using the belt punch, it should not be worked on hard ground in order not to damage the cutting edge. Rubber, cardboard, etc. should be placed under the material to be cut with a punch, in order to prevent the mouths from deteriorating. materials should be placed. Also, while the belt is working with the stapler, the stapler should be kept upright. The point to be considered while using the pin punch is that the difference between the diameter of the punch and the diameter of the pin to be used should not be large. Pin punch suitable for pin diameter should be used.
    A guide suitable for the rivet size should be used in order to avoid any problems during the use of the rivet gun. If the rivet small guide is chosen large, either the rivet will not be able to grip the pin, or the rivet will be stuck in the guide when the pin is grasped. If the rivet large guide is chosen small, either the rivet will not enter the guide, or even if it does, it will get stuck between the jaws that grip the pin of the rivet. In order to prevent these, the appropriate guide for the rivet should be selected.
    When using the wheel wrench, excessive load should not be applied by attaching the extension arm. In this case, the cross key may be damaged because the load is applied much more than the load values ​​specified in the standard. In addition, since bolts and nuts are made according to certain standards, they all have a certain strength value. If a force is applied above these strength values, the bolt may also break. Rust remover should be used when removing bolts that are rusted due to dynamic loads and environmental conditions, or they should be lubricated to facilitate disassembly.
    Super insulated and rod insulated pliers, picks and pliers, within the scope of TS EN ISO 60900 standard, these tools are tested under 5000 Volt voltage, electrical permeability test under 10000 Volt voltage, impact test at -25ºC, handle stripping test at 70ºC, etc. tests are applied. These products can be used safely in high voltage values, extreme temperatures and extreme cold. However, if the isolated part of the handle is deformed in super-insulated ones, especially if the yellow layer under the red layer is visible, the super-insulated tools should not be used in electric current.
    Chisels, point punches, belt punches, pin punches should be used for their intended purpose, not like a crowbar. Extremely tight pins should be removed with a punch after lubrication. Such hand tools are hardened by various heat treatments. When using these tools, over time wears occur on the tips (blinding), it is not recommended to apply sanding or grinding processes that will make the tips lose their hardness. If necessary, grind or sand using coolant.
    Although the tip of the control pen is a flat screwdriver, the main function of the tool is the control of electric current. For this reason, if the tool is exposed to impacts, it may lose its original feature. 
    The shafts of the pullers must not be exposed to impact or impact. The screw part must not be damaged. For the most healthy load distribution, it is appropriate to use a three-arm puller if possible. You need to make sure that the puller is properly positioned on the part to be pulled and should not be worked in front of the puller.
    The functional parts of the circlip pliers used for attaching and removing circlip are very thin end parts, and the tool should not be dropped on the end parts. In addition, suitable circlip pliers should be used according to the diameter of the circlip to be used.
    A torque wrench is used when a bolt or nut needs to be tightened with a certain torque value, or when many bolts or nuts need to be balanced to the same torque value. More or less than the torque value set using the torque wrench is not applied. However, it is not appropriate to loosen long-term, rusted, very tight connections with a torque wrench. It is also not appropriate to try to loosen these tight connections by hammering. In such cases, oil, rust remover or loosening liquids should be applied to the connection and after waiting for a while, bolt or nut removal should be performed with a suitable wrench. In addition, disassembly is definitely not done with a torque wrench.
    Phase Control Pen
    A check pen is a test tool used to find out if there is voltage in an electrical circuit or system.
    Flat screwdriver
    A flat screwdriver is a hand tool used for mounting flat screws (screws with a single diametrically slit in the center of the flat head) to surfaces such as walls, wood, or for driving and removing screws into previously drilled holes for these screws.
    Screwdrivers are manufactured from chrome vanadium alloy steels by hardening in heat treatments in order to increase the resistance to wear on the tips in accordance with the intended use. This high hardness value, which prevents wear on the tips, causes breakage as the screwdriver is exposed to bending. Therefore, do not use your screwdriver as a chisel and crowbar. Fractures that may occur may lead to undesired work accidents, injuries and job losses.

    Another issue that should be considered in the use of screwdrivers is that screwdrivers should be used in appropriate bolts. Flat, Phillips or Pozidriv head screwdriver must be fully seated in the key blade of the screw and grasp from the widest surface. Otherwise, since the gripping surface (contact surface) will be narrow, only the tip of the screwdriver will be loaded and deformed. Although the Pozidriv screw and Phillips screw key blades are similar to each other, if a pozidriv screwdriver is used on a Phillips head screw, the screwdriver bit will not fit into the key blade of the screw and will be deformed. And when using these tools, applying force by passing an extension arm through the hanging hole in the handle will cause the screwdriver to break and deform, as it will exceed the strength value in the standards.

    Phillips Screwdriver
    A Phillips screwdriver has the same function as a flathead screwdriver. The only difference is that the metal tip of the Phillips head screwdriver is used to twist and drive the Phillips screws (screws with two slots in the center of the flat head that cut each other at 90 degree angles across the diameter).
    Two Blade Screwdriver
    Two-bladed screwdrivers were produced with the idea of ​​carrying a single screwdriver with two different blades instead of carrying two different screwdrivers for simple screw tightening and loosening.
    Pliers are manufactured by assembling two identical but symmetrical parts at a fixed point. These two parts, which are symmetrical to each other, can be opened up to about 30 degrees at the point where they are fixed.
    Side Chisel
    The structure of the side cutters is similar to pliers. Again, two identical but symmetrical parts at the fixing point can be opened up to about 15 degrees. Unlike pliers, side cutters do not have teeth on the tip. There are only two opposite sharp metal blades. In this way, operations such as cutting wire and cable, stripping the insulation on the cable, cutting soft metal parts can be performed with side cutters. 
    It has a pliers-like structure. Unlike pliers, the metal tip is longer and is pointed, not blunt, like pliers. It got this name because its shape resembles a bird's beak. With the pliers, you can reach the places that the pliers cannot reach, and especially the electronic circuit elements can be easily held. In addition, during the soldering process, the electronic material is held with a pliers, preventing the heat applied to the material with a soldering iron from damaging the hand. In addition, cable stripping can be done with the sharp parts in the middle of the metal ends of the nose pliers.
    Flat Tip Chisel
    Flat-tipped chisels are hand tools made of good grade carbon steel and used to shape materials such as wood, metal, stone.
    Tweezers, surface contact electronics and very small size screws etc. They are hand tools used to hold materials that are too small to be held by hand. Tweezers of various sizes are widely used in fields such as electronics, cosmetics, optics and chemistry.
    Utility Knife
    Utility knives are a hand tool that is mostly used for cutting paper, cardboard, wallpaper, linoleum, fabric and flooring materials, has a plastic or aluminum handle and its sharp blade can be hidden by sliding it into this handle.
    Metal Hammer
    A metal hammer is a hand tool with a metal head and a handle made of wood, fiberglass or metal, used for striking operations.
    The file is a hand tool that is used to remove chips with the help of the teeth on it, to bring the workpiece to the desired shape and size, to smooth and sharpen the surfaces.
    A hacksaw is a hand tool used to cut metal parts of all sizes and shapes.
    Wood Saw
    A wood saw is a hand tool that has a blade with fine straight teeth and a handle made of plastic or wood, to which this blade is attached with screws, and is used to cut wood and wood.
    The scissors have a pair of metal blades and a two-finger grip. When the fingers are opened and closed, sharp blades fixed to each other at one point overlap and cut materials such as paper, fabric, cardboard and thin plastic.
    Cable Stripper Pliers
    Cable stripper pliers are hand tools that are used to separate the insulated material, which is located on the outside of cables of different diameters and provides electrical insulation, from the cable.
    Impact Breez
    Its main purpose of use is to drill holes in desired diameters on walls, wood and metal surfaces. However, operations such as mowing, polishing and polishing can also be performed with various tips connected to the socket.
    Rechargeable Hand Brew
    Voltage values ​​can be 15V, 18V, 24V, 28V and 32V. As the battery voltage increases, the torque (torque moment) of the drill also increases. they are not as powerful as pulsed bracers operating with mains voltage. For this reason, it is mostly used in wood and plastic drilling.
    Cordless drill
    Cordless screwdrivers are hand tools used for screwing in and having a motor and a rechargeable battery to drive that motor.
    Tape measure
    These meters, which can be made as 2, 3 and 5 meters with spring, can be collected into the box automatically when left.
    Foldable Meter
    These meters, which are similar to the combined form of 20-centimeter rulers, are mostly used by carpenters, and foldable meters are made in 1 and 2 meters.
    It can measure depth, width and thickness up to 20 centimeters with this instrument. Precise measurements can be made at ten percent, five percent and two percent of a millimeter.
    Combination Key Set
    It is a combination of an open-end (fork) key and a star key. Key length varies according to mouth size. Combination wrench sets are used to remove and install nuts and bolts.
    Frog Wrench
    The toad wrench has one fixed and one movable and adjustable jaw. The adjustable jaw is adjusted according to the nut size by turning by a gear. Combination wrench sets should be used in such cases, as the threaded mechanism on the froglet may be damaged when too much force is applied to the bolt or nut. Toad wrenches should only be used when the correct size wrench or socket is not available.
    Allen Key 
    It is a type of wrench used to remove and install hexagonal socket-shaped screws. This type of wrenches are “L” shaped and can be mounted and removed with hexagon socket screws of the same size on both ends.
    Socket Wrench 
    Star Key Set  
    It surrounds the nut or bolt heads from all sides. There are 6-point and 12-point types on the key blades. It can be used to rotate square and hex bolt heads. The advantage is that it provides the best protection for both the user and the equipment. The disadvantage is that there must be sufficient clearance above and around the bolt and nut for tightening or loosening.
    The upper jaw can be moved to different positions by sliding it up and down along a plane above the lower jaw. The advantage of this design is that large and different sizes of bolts and nuts can be removed and installed from the desired position with a single hand tool with the pliers.
    It is a device used to store and apply oil, which has gears or pistons (engine, etc.) in its structure and is applied to machines in order to minimize friction.
    It is a hand tool mostly used to break up concrete surfaces and make marks on surfaces to be drilled with brazier.
    It is a tool used to hold or fix the workpiece so that operations such as drilling, cutting, screwing and filing can be done correctly. There are two jaws on the vise and one of them is fixed. The other jaw is movable and is brought closer to the fixed jaw with a screw rotated by one arm and performs the holding or fixing process.
    Hand tool for removing bearings, bearing housings, bushings and oil seal rings.
    It is a tool that is used to remove materials such as paint on the surface of materials that are easy to shape, such as wood, or to shape the wooden material by abrading it from its surface.
    Sharpening Stone
    A whetstone is a circular tool rotated by an electric motor or human power, used for grinding or sharpening the surfaces of iron hand tools.
