Hex socket head screw according to the grade of different, its anti-loosening coefficient will be different, especially in connection with the workpiece often moving, after a long time, may be loose, so what do we need to make hex socket head screw anti-loosening effect is better, anti-loosening longer?

1, increase the friction between the hexagon cup head screw and the connector, can add spring pad to increase the friction, and then use with flat pad can better protect the surface of the workpiece.

2, dispensing process, can be covered with anti-loose glue hex screw thread, so that the anti-loose effect of screw installation will be much better.

3, you can directly buy anti-loose screw, custom-made anti-loose screw anti-loose effect is better
