Description


The Interlock® rivet is a hole filling, multi-grip, structural breakstem rivet available in steel or aluminum construction. Multi-grip means the rivet has the capability to join component parts having a broad range of thicknesses, thus reducing inventory where a variety of rivet sizes might otherwise be necessary. Hole filling means the rivet will expand radially into the application hole to provide a strong, vibration resistant joint and compensate for irregular, oversized, slotted or misaligned holes. Also, it can stop sheet movement in applications with non-standard holes.

However, the main feature of the Interlock® rivet is an internal, mechanical locking feature where the portion of rivet mandrel remaining after rivet placement is captured within the rivet. This action creates a seal at the rivet head and provides superior vibration and water resistance. The mechanical lock is accomplished without a special nose tip so the Interlock® rivet can be installed at a lower per piece cost than other locking mandrel rivets that require special tooling.
