This 5/16" split lock washer is made from 316 stainless steel to resist corrosion in marine, outdoor, and industrial environments. The split-ring design applies constant tension to maintain bolt tightness under vibration or dynamic loading. It’s ideal for fastening jobs where reliability and resistance to loosening are essential. Use it in HVAC, machinery, and exposed structural applications.

Install washer under the fastener head or nut, and tighten until it flattens slightly to activate locking tension.

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.
