Socket wrench is suitable for disassembly and assembly of small bolts

When using a sleeve, remember to choose a sleeve Socket sets that fits the nut or bolt completely. If a sleeve larger than the nut or bolt is used, the sleeve can easily round the head of the nut or bolt during rotation. . When disassembling relatively tight wheel bolts, if you put a suitable extension rod on the sleeve handle, the rotation torque can be increased, and the wheel bolts are easier to loosen. It is important to note that if you use the sleeve handle to extend the rod when tightening the wheel bolts, remember not to use excessive force to prevent the rotation torque from exceeding the bearing range of the nut or bolt, otherwise the nut or bolt will be easily damaged. The application of socket Phillips wrench is suitable for screwing bolts or nuts with very narrow positions or deep recesses. The socket wrench is suitable for disassembly and assembly of small, particularly concealed bolts or nuts.

The sleeve part is similar to the end of a torx wrench and is made into a single piece. According to needs, sleeves of different specifications and various handles can be used for combination. For example, the movable handle can adjust the required moment arm; the quick handle is used to quickly disassemble bolts and nuts; at the same time, it can be equipped with a torque wrench to display the tightening torque, which has the characteristics of multiple functions, convenient use, safety and reliability. The socket wrench is composed of a set of plum blossom tubes of different sizes, which are rolled successively with a bow-shaped handle when in use, and the work efficiency is high. When the size of the screw or nut is large or the working position of the wrench is very narrow, a ratchet wrench can be used. This kind of wrench has a small swinging point of view and can tighten and loosen screws or nuts. Turn the handle clockwise when tightening.

A support rod is installed on the square sleeve. When the handle is pulled back in the opposite direction, the strut slides out in the inclined surface of the ratchet teeth, so the screw or nut will not follow the reversal. If you need to loosen the screw or nut, just flip the ratchet wrench and roll it counterclockwise. Precautions for the use of socket wrenches: Wear gloves when using it. For the selection principle of various wrenches, socket wrenches are generally preferred, followed by box wrenches, open-end wrenches again, and adjustable wrenches last. The opening size of the selected wrench must be consistent with the size of the bolt or nut. If the opening of the wrench is too large, it may slip and hurt your hands and damage the hexagon of the screw. Pay attention to removing the dirt and oil in the sleeve at any time. Grease is not allowed on the jaws of the wrench or on the screw wheel to prevent slippage.

Ordinary wrenches are designed according to the strength of human hands. When encountering tighter threaded parts, you cannot hit the wrench with a hammer; except for socket wrenches, no other wrenches can be fitted with an afterburner to prevent damage to the wrench or threaded connection. . In order to prevent the wrench from being damaged and slipping off, the pulling force should be applied to the thicker side of the opening. This is especially important for adjustable wrenches with greater force to prevent the opening of the "eight" shape and damage the nut and wrench. The choice of tools according to the type of work is to remove and replace bolts/nuts or remove parts. It is more common to use a set of socket wrenches in car repairs. The use of a socket wrench to choose a tool according to the speed of work is that it can rotate bolts/nuts. No readjustment is required, which allows the bolt/nut to be quickly turned. The socket wrench can work in various ways according to the installed handle.
