Description

3/8" Conquest Split Lock Washer - 316 Stainless Steel

This 3/8" split lock washer delivers mechanical tension and corrosion protection for structural and mechanical fastenings. Made from 316 stainless steel, it resists rust and degradation in saltwater, chemical, and humid conditions. The split-ring form acts as a spring under compression, preventing bolt rotation and back-off during vibration or load cycling.

Position washer under the bolt head or nut, tighten until slight compression is observed to activate the locking action.

Whether used on equipment frames or marine hardware, this washer keeps connections secure in demanding environments.

Key Features

  • 316 Stainless Steel: Maximum corrosion resistance for marine and chemical exposure.
  • Split-Ring Form: Maintains bolt preload and resists loosening.

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.
