Everyone knows what a screwdriver is for. This tool is simply indispensable for a variety of types of work. But a special place deservedly belongs to triangular screwdrivers.
The recommendations of experienced builders, as well as the advice of sales consultants and especially television programs on construction and repair, convinced many people that working with fasteners should be done with an electric tool. And in many cases this is true. But still there are a number of situations where manual devices cannot be dispensed with. The advantages of any screwdriver are:
- ease of use when attaching very small parts;
- possibility of use where any screwdriver gets stuck;
- ease of use regardless of the stability of the power supply or at high humidity;
- storage even in tight spaces;
- the possibility of applying for repairing not only building structures, but also cars, household appliances, toys and so on.
A triangular screwdriver is fully consistent with this description. But it differs from the cross-shaped and flat options.
Thanks to the tip resembling an isosceles triangle, this tool is mainly used when working with kitchen appliances. After all, almost all firms that produce this technique try to prevent accidental penetration of non-specialists into its internal parts. Therefore, the fasteners began to make an unusual shape.
If no suitable tool
Sometimes a problem occurs when a triangular screwdriver is not at hand. In such cases, there is no need to use brute force and crack the kitchen appliance body. It is enough to replace the store tool with a do-it-yourself tool. A suitable analogue is obtained from a hex key for furniture. It is included in the package of the closet and any other independently assembled items.
Furniture suppliers intentionally make them from soft enough metals to save on processing. But still, you can make a good tool for repairing household appliances. It will only be necessary to remove the excess part of the hexagon. For cutting, an abrasive wheel mounted on an engraver is preferred. Usually it takes no more than ¼ hours and 1–2 adjustments to make a triangular screwdriver as good as the one included in the store kit.
Triangular screwdrivers are needed when repairing not only kitchen appliances, but also personal computers, as well as various kinds of mechanical toys. If you have to work in hard-to-reach areas, it is worth using a tool with a bending shaft. It is advisable that the kit includes screwdrivers suitable for removing tight (corroded) fasteners. As for manufacturers, to buy products of leading German and Japanese brands need only professionals. In domestic conditions, the opportunities provided by "factory China" are quite enough.
Important: a triangular screwdriver, like any other, can only be used for its intended purpose. It can not be replaced with a knife, corkscrew, wedge, lever, prop and other devices.
Do not use damaged tools. Before starting work, you should carefully inspect the screwdriver to make sure it is fully operational. If you suddenly cannot turn the screw or other fasteners, you should not try to do this with maximum effort - otherwise there is a high risk of damage to the tool, material, fasteners or even injury.
Screwdriver sets should only be stored and transported in specially prepared cases or portable carry cases. You can not carry them in your pocket. When the fastener is screwed (unscrewed), it is forbidden to hold the workpiece in your hand.
The handle of the screwdriver must be kept clean, carefully avoiding contact with lubricating oils. Violation of such rules threatens to damage property or even an accident.
Experts strongly advise to disassemble all household appliances and electronics only in the off state. Even under this condition, exclusively insulated (dielectric) screwdrivers should be used. Protect the blade and handle from heat. It is strictly forbidden to rotate the handle clamped in pliers: instead of enhancing the effect, this will destroy the tool. You can not make nicks and markings with a screwdriver, stir construction paint.
