What is a combination wrench

Combination Socket sets wrenches are also called dual-use wrenches. They are composed of a torx wrench and open-end wrench. One end is an open end and the other end is a torx end. This combination wrench is very convenient to use. In the tightening process, you can use the open end to screw the bolt to the end, and then use the toe end to complete the final tightening, and when loosening, use the toe end first to better protect the corners of the bolt or nut. Do not use the open end for the final tightening operation, if you must use an open end wrench for the final tightening. Open-end wrenches can only pull the bolt or nut in a limited space. After the bolt or nut is pulled to the limit position, take out the wrench and repeat the original process. The direction of pulling the wrench should be in the direction of the attached jaws.

When using an open end wrench for final tightening, the force applied to the wrench cannot be too large, otherwise it will cause thread slippage. The hand should be completely clamped on the bolt to increase the contact area. Only use wrenches with the same size as the bolts or nuts. If the size of the wrench is too large, the bolt or nut will be damaged. Wrong use of the wrench can damage the wrench or bolts and nuts. Tight operation should be completely in accordance with the torque requirements of the bolt or nut, and it should not be too large, otherwise it will cause damage to the corners of the bolt or nut.
