S637045 - Light Duty and Medium Duty Safety Washers

This range of safety washers is based on the disc spring concept. The washer has the unique feature of radial serrations on both the concave and convex surfaces. When final flattening of the serrated safety washer occurs with the tightening of the screw, the serrations bite into the mating faces, thus preventing loosening of the screw caused by vibration.

The disc spring profile will also assist in retaining the required screw tension.

The safety washer offers a reduced outside diameter compared with a conventional disc spring a Belleville spring washer. This corresponds to most screw head sizes and is very compatible with the hexagonal socket type screw.
