Description

5/16" Conquest Split Lock Washer - 18-8 Stainless Steel

This 5/16" split lock washer provides vibration resistance and corrosion protection in one reliable component. Made from 18-8 stainless steel, it performs well in outdoor, marine, and industrial applications. The split-ring shape exerts continuous spring tension under load, helping prevent bolt or nut loosening in dynamic assemblies. It’s a dependable choice for automotive, HVAC, and general fabrication projects.

Position beneath bolt head or nut with offset split ends, and tighten until the washer compresses slightly.

just what I wanted and only what I wanted

I got the bolts, nuts and washers I needed to add a more robust safety catch to my pro leg press. This personal project was one I had to put off because local shops (lowes, home depot) did not have the parts. I got them from fasteners plus fast in multiple mail orders.
