Socket wrench is composed of multiple sleeves with hexagonal holes or twelve-corner holes and equipped with handles, adapters and other accessories. It is especially suitable for twisting bolts or nuts with very narrow or deep recesses.For the nut end or bolt end is completely lower than the connecting surface, and the diameter of the concave hole cannot be used for open-end wrenches or adjustable wrenches and torx wrenches, socket wrenches are used. In addition, the space of the bolt parts is limited, and socket wrenches can only be used.The sleeve is divided into metric and imperial systems. Although the inner concave shape of the sleeve is the same, the outer diameter, length, etc. are designed for the shape and size of the corresponding equipment. The country has no uniform regulations, so the design of the sleeve is relatively flexible and meets the needs of the public.Socket wrenches are generally equipped with a set of socket heads of various specifications, as well as swing handles, adapters, universal joints, screwdriver joints, elbow handles, etc. for inserting hexagonal nuts.The socket head of a socket wrench is a concave hexagonal cylinder; the wrench is usually made of carbon structural steel or alloy structural steel, the wrench head has a predetermined hardness, and the middle and handle parts are elastic.There are two reasons for the lengthening of the sleeve: one is that it can be easily reached to places that are difficult to reach; the other is to lengthen the arm so that when the same force is used, the torque will be large.It is convenient to remove some tighter screws.
