The function of this kind wrench is used as to the principle of leverage to turn bolts, screws or nuts to achieve a tight or loose thread. Dual-purpose spanner usually has an opening for clamping bolts or nuts at one end of the handle, and a plum sleeve hole for clamping bolts or nuts at the other end. When used, the bolt or nut can be turned by applying external force in the handle along the direction of thread rotation. Dual wrench is a common hand tool for installation and disassembly.

The size of the opening and the plum hole at both ends of the wrench is fixed, so a dual-use wrench can only fasten or remove a fixed size nut or bolt. Therefore, the general dual-use wrench needs to be bought in sets, size specifications from 3.5mm-80mm, among which the most commonly used size is 6-32mm.

Precautions when using wrench:

1.Choose appropriate wrench according to the size of the bolt or nuts. If the wrench is too large,it is easy to slip or damage the nut or bolt.

2.The pliers of the wrench should be completely closed to two opposite edges of the bolts and nuts.There should be no space between to prevent slipping so as not to damage the pipe fittings or nut,or cause injuries to users.

3.Do not use the wrench as a hammer,wrecking bar,etc.

4.It is not allowed to stand within one meter of wrench forcing direction.It may hurt people around.

5.Keep the moving part clean and scrub it after use. It is better to wipe the wrench oil in a period. Put it back in the plastic case for storage.
