The Interlock rivet is a hole-filling, multi-grip, structural break stem 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 the 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.

• Multi-grip capability good sheet take-up performance
• Wide choice of installation tools
• High shear and tensile strength
• Good sheet take-up performance for large gap-closing capability
• Excellent hole fill via radially expanded body provides very strong, vibration-resistant joints and compensates for irregular, oversized, slotted, or misaligned holes
• Stem mechanically locked into the body
• One fastener can be used to replace several standard grip fasteners
• Reduced fastener inventory and simpler stock control
• Compensates for irregular, oversized, slotted, or misaligned holes
• Can stop sheet movement in non-standard holes
• Large gap-closing capability
• Provides very strong, vibration-resistant joints
• No damage, electrical problems, or rattling due to loose stems
