Rivets
Lockbolts
Lockbolts are two-piece fasteners with a grooved pin and a collar that is swaged into the pin grooves under load. The swaged joint gives consistent clamp force and strong resistance to vibration loosening.
Used in trucks, trailers, rail, and heavy equipment where a bolted joint must not loosen in service. Buyers are vehicle and equipment manufacturers replacing rivets or high-grade bolts.
