The Disc-Lock® Safety Wheel Nut is specifically designed to prevent wheel loss from commercial vehicles such as trucks, trailers, and buses. Disc-Lock Safety Wheel Nuts have been proven to provide better joint protection than standard wheel nuts. The combination of lateral, bending forces on the wheels due to cornering, and torsional forces due to braking and acceleration cause Disc-Lock Safety Wheel Nuts to lock, maintaining clamp force.

Disc-Lock's Safety Wheel Nut consistently performs with class 8.8, Grade 5 bolts and come in size M22

The Disc-Lock Three-Piece Locking Nut consists of three components:

1. Nut
2. Hexagon-flanged Washer
3. Flat-faced Cup Washer

These sections are joined together to form a one-piece assembly with a C-clip.

The top two sections (1 and 2) are a hexagonal nut and a hexagonal washer with interlocking cams.

Installation & Removal
The Disc-Lock Safety Wheel Nut is easy to install and remove. It is installed in exactly the same way as a standard wheel nut. Place the socket over the hexagon nut and hexagon flanged washer and tighten or loosen.
