Variant No1. Phillips head slot

Types of screws
To begin with, a screw is a cylindrical rod with a special head, on which a screw groove is applied. Screws are produced according to a number of standard documents, including GOST 1144-80, GOST 1145-80, etc. д.
At the same time, there are two main types of hardware. these are:
For designation in this case are used diameter and length of the screw (for example, a product with a diameter of 5 mm and length of 3.5 cm will be referred to as 5×35 mm). In addition, hardware can be classified according to the shape of the slot and the features of the head itself:
All of these varieties are made with a cross-shaped slot, with a straight (flat) and with a Torx slot (the latter is also known as a star), as well as with an internal hexagon and other, less popular variants. There are also screws with the head of the six-and octahedral shape (roofing), which are also made with different slots.
For your information! According to the type of thread screws are also divided into several varieties, which is conditioned, first of all, by the connected materials and the specific purpose (for metal, wood, drywall or small household appliances).
If you don’t have a suitable tool
Occasionally a malfunction occurs when a triangular screwdriver is not to hand. In such cases, there is no need to use brute force and break into the body of the kitchen appliance. It is enough to replace the store tool with a tool made by your own hands. A comparable one is made from a hexagonal furniture spanner. It is included in the set of a closet compartment and any other self-assembled items.
Furniture suppliers deliberately make them from soft enough metals to save on machining. But it is still possible to make a good repair tool for 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. It usually takes no more than ¼ hour and 1-2 tweaks to get a screwdriver as good as the one in the store set.
Another option is to use a toothbrush. Heat one end with a lighter, and then immediately insert it into the groove in the screw head. After waiting a bit for the melted plastic to solidify, turn the brush counterclockwise. Of course it doesn’t help if the screw is tightened too much.
