The lock nut can effectively improve the assembly accuracy, improve the deflection of the spindle, is easy to install, not easy to loosen, and can prolong the service life of the workpiece. Widely used in precision mechanisms. The lock nut is easy to assemble. Tighten to-rated tightening torque using a hook wrench or insert wrench. The required tightening torque depends on the required pre-tightening. When pre-tightening the nut body, pass the Allen key and tighten Tighten until the locking screw is blocked. Then tighten the screws one by one. Below, 2H Heavy Hex Nuts Manufacturers describes three ways to use lock nuts:

1. Use two identical nuts to tighten the same bolt and increase the tightening torque between the two nuts to ensure the bolt connection.

2. Lock nuts should be used with lock washers.

3. From the outer surface of the nut to the surface of the inner thread, there are several screw holes (usually two screw holes, distributed in a ratio of 90), which are used to tighten small-diameter countersunk head screws. The centripetal force prevents the locknut from loosening.
