Serrated Disc Washers

Serrated disc springs are a form of disc spring serrated on both sides of a trapezoid cross section. Because their diameters are matched to screw dimensions, the serrated disc springs can be used with practically any screw or bolt. The outer diameter of the serrated disc spring will match up to the head diameter of pan head and hexagon socket head cap screws, including recessed heads.

CAD files for stock and standard serrated disc washers are available for download in MW OnDemand.

Custom Serrated Disc Washers

All our disc springs are subject to exacting manufacturing and quality control standards. All discs are preset so that they will not significantly relax under load over time. MW also offers pre-stressed disc springs specifically sized for use with bolts.
