A wrench is a common mounting and removal tool. Use the principle of leverage to twist bolts, screws, nuts, and other hand tools that hold the opening or socket firmware of the bolt or nut. The wrench usually has an external force applied to the one end or both ends of the handle to apply an external force to the external force of the handle, so that the bolt or nut can be screwed to the opening or sleeve hole of the bolt or nut. When using, apply an external force to the shank in the direction of thread rotation to twist the bolt or nut. Wrenches are usually made of carbon structural steel or alloy structural steel.
The double-headed open-end wrench is made of 45# medium carbon steel. There are many types of electric open-end wrenches, plum blossom open-end wrenches and so on.
Commonly used open-end wrench specifications: 7, 8, 10, 14, 17, 19, 22, 24, 27, 30, 32, 36, 41, 46, 55, 65. Corresponding thread specifications are M4, M5, M6, M8, M10, M12, M14, M16, M18, M20, M22, M24, M27, M30, M36, M42.
