Product details
All Metal Lock Nuts are prevailing torque lock type nuts with no non metallic insert. These All Metal Lock Nuts have a conical top and a flat bottom bearing surface with chamfered corners. The locking action, created by distortion of their top threads, is said to resist loosening caused by shock, vibration and other dynamic forces. Since they are top locking and only the bottom surface is flat, prevailing torque lock nuts are considered one way lock nuts because they are installed one way - conical top up. Being all-metal, they are not subject to the temperature and chemical limitations of non-metallic inserts.
