Hi Lock Washer

The Hi Lock Washer (Part Number 3-09A) is a precision fastening component designed for specific applications in transmission builds and drivetrain security. It is engineered to provide reliable fastening in environments where vibration and torque are significant concerns. This washer is particularly suited for professional transmission builders and automotive enthusiasts who prioritize drivetrain integrity.

Manufactured by BERT TRANSMISSIONS, the Hi Lock Washer features a high-lock design that effectively resists loosening due to vibration without the need for additional locking elements. Its compact dimensions (1.1 x 0.3 x 2.95 inches) and lightweight construction (0.04 lbs) make it ideal for integration into tight spaces within transmission assemblies. The washer's geometry is optimized to maintain clamping force under repeated shock loads and thermal expansion cycles.

This Hi Lock Washer is best utilized in performance transmission builds, where the demands of high-RPM operation and thermal cycling are prevalent. Builders and restoration shops can rely on this component to enhance the reliability of their assemblies, ensuring that fastener failure is minimized in critical applications.
