Screw manufacturers tell you what is torquescrew manufacturers tell you what is torque
In daily life, we always use screws to install or fix some things. However, sometimes in the process of using screws, the screws will break due to too much force. Many people think that it is improper operation or the quality of the screws is too bad. but I never thought that the torque cause this issue
Screw torque refers to the degree of tightening of the screw and the breaking force of the screw. Once the force of twisting the screw exceeds the torque of the screw, it is easy to cause deformation and fracture inside the screw, which will bury hidden dangers for the product. Therefore, we must control the screw tightening force not to be higher than the screw torque. The following Shenzhen Heat Hardware Co.,Ltd screw manufacturer attaches a common screw torque standard table for your reference:
Type A: Fixation between steel screw and steel nut (screw hole).
Type B: Fixation between steel screws, copper nuts (screw holes) and aluminum alloy screw holes.
Type C: steel screws (self-tapping) are locked in plastic holes.
Type D: The steel screw (self-tapping) is locked in the threaded hole with a thickness of 1.0. M3 extraction hole is ф2.8(+0,-0.05), M4 extraction hole is ф3.65(+0.05,-0)
Type E: The steel screw (self-tapping) is locked in the extraction hole with a thickness of 1.2, and the size of the extraction hole is the same as item D.
