Disc-Lock’s superior fastening systems are used across a wide range of industries where vibration is an issue.

Our washers and nuts are heavy-duty structural locking devices recommended for the most stressful, dynamic applications. From trucks and trailers to mining equipment and heavy machinery - Disc-Lock products provide a fit and forget solution.

The system is a simple one. Interlocking cams rise against each other to create a wedging effect that locks the assembly together and maintains tension. Joint integrity is guaranteed and once installed, the fastener remains fully secure with no need for retightening.
