PEM® S-RT FREE RUNNING SELF LOCKING NUTS
S-RT free running self locking nuts are a game changer in the world of captive self locking nuts. Most self locking nuts are of the prevailing torque type which put a drag on the mating bolt whilst it is being tightened, as is obviously demonstrated in nylon insert nuts. S-RT avoids this and is almost endlessly reusable without loss of its self locking efficacy. S-RT nuts reduce assembly time, the number of components required, and improve self locking performance.
