Self Locking Nuts

Fastenright supply a wide range of self-locking nuts for various applications.

Lock nuts (also known as prevailing torque nuts or stiff nuts) are resistant to vibration & torque. They are primarily available in stainless steel and other finishes.

Their locking action is created by the distortion of their uppermost threads and should resist loosening caused by shock, vibration and other forces. They host a self-contained feature which creates frictional interference between the threads of mating components.

Locknuts are reusable a limited number of times as the prevailing torque declines each time the nut is used.
