Screw standard tightening torque

According to the material classification of the screw, it can be roughly divided into: 1. Standard T series (material: SS.SC): ordinary fastening, as far as possible, the series should be used as much as possible;

2.0.5T series (CR, CB, AB): Screw, internal thread, fastening body is made of copper, aluminum, plastic, etc. Die-casting products plastic parts (electronic products);

3.1.8T series (SGr, SNC, SCM) adopts the special threaded joint of special steel, especially when the bolt is subjected to additional dynamic load (vehicle, engine);

4.2.4T series (SGr, SNC, SCM, SNCM): Strong threaded joints made of special steel, especially when the bolts are only subjected to static load (friction combined) for construction.

The following is the nominal diameter, T series and tightening torque corresponding value table (N.M):
