Hex Jam Nuts

Hex jam nuts are thinner than a standard hex nut but have the same dimension across the flats and corners. A jam nut can be threaded onto a bolt and run tight against the standard nut which will lock the nut in place and prevent it from backing off. Jam nuts are sometimes used for leveling purposes as well.

Three advantages of hex jam nut:

First, superior anti-vibration performance: when the thread is tightened, the top thread of the bolt is tightly inserted into the 30°wedge-shaped bevel of the nut, and the normal force generated by the wedge-shaped inclined surface is applied to the bolt. The axis is at an angle of 60° instead of 30°. Therefore, the normal force generated when the hex jam nut is tightened is much larger than that of the ordinary standard nut, and it has great anti-loose and anti-vibration capability.

Second, the wear resistance and shear resistance are strong: the 30° bevel of the nut thread base can evenly distribute the nut locking force on the threads of all the thread, because the pressing force on each thread surface is evenly distributed, so The nut can better solve the problem of thread wear and shear deformation.

Third, the repeated use performance is good: a large number of uses indicate that the lock nut is repeatedly tightened and disassembled after repeated times, and the locking force is still not reduced, and the original locking effect can be maintained.
