C-LOC™
Collar Type Prevailing-Torque Locknut
The C-LOC™ is an all-metal fastener designed to provide a secure and vibration-resistant connection in various applications. This locknut features an oval-shaped locking collar at the top, which creates frictional thread interference during installation, ensuring a reliable lock.
C-LOC™ locknuts are engineered to maintain joint integrity under conditions involving continuous heavy vibration, shock, extreme temperatures, and numerous loading cycles. The oval locking collar deforms elastically when tightened, creating a prevailing torque that resists loosening without the need for additional locking devices. This self-locking feature is crucial in applications where maintaining consistent clamping force is essential for safety and performance.
Application
C-LOC™ locknuts are suitable for a wide range of applications, including:
- Automotive Industry: Securing components subject to constant vibration and dynamic loads.
- Machinery and Equipment: Maintaining the integrity of assemblies in industrial machines operating under harsh conditions.
- Aerospace Sector: Providing reliable fastening solutions in environments with extreme temperatures and mechanical stresses.
Specifications
Sizes

Installation
The installation process for the C-LOC™ locknut is straightforward:
Threading
Manually spin the locknut onto the bolt until it contacts the bearing surface.
Seating
Continue to tighten the locknut using an appropriate wrench until it is firmly seated against the base.
Locking
As the nut is tightened, the oval locking collar deforms elastically, creating a prevailing torque that secures the nut in place.
This method ensures a secure and maintenance-free fastening without the need for supplementary locking devices.
