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.

Non sparking socket wrench

The material of non sparking tools: Al-Br(QAl11-4-4), Be-Cu(QBe2)

Be-Cu: the color is green lake,hardness is not less than HRC35,tensile strength δ b 105-120kgf/mm2;standard code GBEX ⅡC,suitable for hydrogen with concentration 21.0±2.0%.Beryllium copper alloy with anti-magnetic performance.

Al-Cu: the color is bluish yellow,hardness is not less than HRC25,tensile strength δ b 75-85/mm2;standard code GBEX ⅡB,suitable for ethylene with concentration 7.8±0.5%,GBEX ⅡA (propane 6.5±0.5%),Ⅰ(methane 6.5±0.5%)。

Non sparking tools of XIN DA are made of high strength copper alloy.This kind hand tools can effectively prevent burning and explosion accidents caused by friction and collision between tools and tools in the flammable and explosive workplace.The explosion-proof performance received the certificates according to the national standard GB10686-2003, with the function of high intensity and good toughness.

The products are widely used in petroleum,chemical industry,mining,gas,coal,oxygen-producing,pharmacy,smelting,powder,leather,airplane,marine engineering etc,suitable for warehouse that operate flammable and explosive products,electrolytic workshops,communication assembly workshops,and requires that the tools are not rusty,wear-resistant and anti-magnetic during the checking process.
