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.

316 Stainless Steel Lock Washers.

We build very long lasting bird homes. After constructing a wooden frame we weld HDPE for the entire shell. Even the screws we use for the frame are 316 Stainless. Most of our hardware is purchased from these fine folks we’ve been doing business with for sometime. Our experience has been nothing but positive. Of course there’s gonna be some glitches in any lasting business relationship and any of the very few we’ve had has been rectified with a short phone call. And to be honestly embarrassed, not all the “glitches” have been on their side of the fence. Thanx Folks!

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.
