The socket wrench is composed of a plurality of sockets with hexagonal holes or twelve corner holes, and is equipped with a variety of accessories such as handles, posts, etc. It is particularly suitable for turning bolts or nuts with very narrow positions or deep recesses.
For nut ends or bolt ends that are completely lower than the surface to be connected, and the diameter of the recessed hole cannot be used for open-end wrenches or adjustable wrenches and box end wrenches,these conditions will be used socket wrenches. In addition, due to space limitations of bolts, only sockets wrench is suitable.
Socket wrench can be divided in to metric and inch. Although the sockets have the same concave shape, the outer diameter and length are designed according to the shape and size of the corresponding equipment. There is no uniform national regulation, so the socket wrench design is relatively flexible and meet the needs of the public.Socket wrenches are usually used with a set of socket heads of various specifications and handles, extension bar, universal joints, offset handle, etc..
The socket head of a socket wrench is a concave hexagonal cylinder; the non sparking wrench is usually made of beryllium copper or aluminum bronze. The wrench head has a specified hardness, and the middle and handle parts have toughness.
