Because stainless steel has good ductility, it is essentially different from carbon steel. Improper use will cause the Hexagon Flange Bolt to be unable to unscrew after being matched with the nut, that is, “locking” is commonly known as “seizing”. The main prevention of locking is the following aspect:
1. Choose the right product
A. Reasonably choose the length and specifications of the screw, and the 1-3 pitch of the nut after tightening shall prevail;
B. Before use, confirm whether the mechanical properties of the product can meet the use requirements;
2. Reduce friction coefficient:
A. The thread surface is clean (such as no sand, debris)
B. It is recommended to coat the surface with water wax or add lubricant (such as butter, 40# engine oil);
3. Correct operation method:
A. The screw must be perpendicular to the axis of the thread, and do not tilt;
B. During the tightening process, the force must be even, and the tightening torque must not exceed the safe torque;
C. Threaded Rods And Eye Bolts use torque wrenches or socket wrenches as much as possible, and avoid using adjustable wrenches or electric wrenches;
