b. Clean thread surface (no ash sand, blasting slag, debris).

2. Correct operation method:
a. Must be perpendicular to the axis of the thread, do not tilt.
b. In the tightening process, the force must be uniform, and the tightening torque must not exceed the safe torque.
c. Use torque wrenches or socket wrenches whenever possible and avoid adjustable wrenches or electric wrenches.
