1) Description of Ring-Grooved Lock Botls
Superior vibration resistance and durability for heavy-duty applications
Whereas conventional bolts are set using a nut, a ring grooved lock bolt is set using a permanent sleeve

The collar is fitted into a pre-drilled hole and as the collar is tightened,
It is squeezed and forced into the grooves of the pin to swage the collar.
