Socket Wrench, A Must Have for Auto Repair and Maintenance Tool

A socket wrench is composed of multiple sockets with hexagonal or twelve-pointed holes and is equipped with various accessories such as handles and rods. It is especially suitable for bolts or nuts in very narrow screw or deep positions. It is a special tool for tightening or loosening screws. It consists of several inner hexagonal sockets and one or several handles on the upper sleeves. The inner hexagonal sockets of the sleeves are arranged in sequence according to the bolt type, and can be selected according to needs. The utility model relates to a water supply pipe connecting fitting, which can be used for connecting steel pipes and cast iron pipes and the like.

The sleeve also has a steel bar connection sleeve, a special product for the mechanical connection of steel bars, which is divided into cold extrusion sleeves, tapered thread sleeves and straight thread sleeves.

Sockets are available in metric and imperial
Socket wrench specifications are generally different due to the calculation methods in different countries. For example, in China, the socket wrench is calculated according to the metric system, and in some other countries, they use the imperial system. Since the metric and imperial system has some omitted mantissas, there are some differences in the size of the product specifications, but generally speaking, it is still common. According to the different conversion units at home and abroad, they are also different from the machines produced, so the required socket wrenches are also somewhat different, but generally socket wrenches are used for car maintenance and machine maintenance. Therefore, you only need to purchase metric products in China, except for some emerging equipment imported from abroad.

Although the concave shape of the sleeve is the same, the outer diameter, length, etc. are designed according to 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 attached with a set of socket heads of various specifications and swing handles, extension rods, universal joints, screwdriver joints, elbow handles, etc. for inserting hexagonal nuts. The socket head of the socket wrench is a concave hexagonal cylinder; the wrench is usually made of carbon structural steel or alloy structural steel, the head of the wrench has a specified hardness, and the middle and handle parts are elastic.

When using a socket, you do not have to choose a socket that fits perfectly with the nut or bolt. If you use a socket larger than the nut or bolt, the socket will easily round the head of the nut or bolt during rotation. . When removing tight wheel bolts, if a suitable extension rod is put on the socket handle, the rotation torque can be increased, and it is easier to loosen the wheel bolts. Special attention should be paid to the fact that if you use the sleeve handle extension rod when tightening the wheel bolts, remember not to use too much force to prevent the rotational torque from exceeding the bearing range of the nut or bolt, otherwise the nut or bolt will be easily damaged.
