What Should We Pay Attention to When Using Wrenches?

Wrenches are used to install and dismantle machine parts, usually made of carbon structural steel or alloy structural steel, divided into many types, it has been the majority of consumers love with its excellent performance. But its use should also pay attention to some security issues.
1.force evenly, the operator must be evenly engaged in the pull wrench, only in this way can it open parts more quickly. The uneven force will cause trouble, because suddenly pulled the wrench will produce impulse, and in the moment to stop the force, perhaps the screw or bolt has been turned over, then it will affect the use of efficiency.
2.Clean up debris in time, before operating the wrench, should clean the surrounding contaminants, otherwise it will affect the exact torque value.
3.Consider the friction factor, the use of wrenches will produce friction, so when using the wrench, all these frictional factors should be taken into account.
