Lock Collars

Lock Collars for Automotive Structural Fastening Systems

Lock collars are an essential component of lock bolt fastening systems used throughout the automotive and transportation industries. Installed together with a lock bolt pin, the collar is permanently swaged into place to create a high-strength, vibration-resistant joint capable of withstanding demanding operating conditions.

Automotive manufacturers rely on lock collar systems in structural assemblies where safety, durability and long-term performance are critical. By providing consistent clamp force and resistance to loosening, lock collars help maintain the integrity of vehicle structures throughout their service life.

At FACIL, we offer a range of lock collars designed to meet OEM and Tier supplier requirements for automotive and industrial applications.
