Tips: How to use a box end wrench?

When using the box end spanner, hold the connection point of box end spanner and the bolt with your left hand. Keep the box spanner in perfect coordination with the bolt to prevent slipping off. Hold the other end of the spanner with your right hand and apply more force. The spanner can be used to enclose all the heads of bolts and nuts, so that the bolt angle will not be damaged and large torque can be applied.

What should I pay attention to when using a box end spanner?

1. When choosing a box end wrench, the size of the bolt or nut must be appropriate, so that there will be no slip during use.
2. 12-ponit box end wrenches are precise and easier fit than 6-point box end wrenches.
3. If the spanner is damaged or cracked, please do not use it to prevent yourself from being hurt.
4. When using the box end spanner, the bolt or nut should be firmly clamped, otherwise the bolt and nut will be damaged.
5. It is not allowed to cover the pipe on the box spanner in order to increase the length of the spanner, which will not only damage the spanner, but also damage the bolt and nut.
