Description

1/2" Conquest Split Lock Washer - 316 Stainless Steel

Built for strength and long-term durability, this 1/2" split lock washer features a corrosion-resistant 316 stainless steel construction. Its split-ring design maintains spring tension under load, reducing the risk of fastener loosening due to vibration or thermal cycling. Perfect for marine, industrial, or high-humidity applications, it offers consistent locking performance in harsh conditions.

Install under the fastener head or nut and torque until the washer compresses slightly to lock the fastener in place.

1/2" Split Lock Washer – Anti-Vibration Locking with Marine-Grade Protection

Use this washer to safeguard against bolt loosening and corrosion where strength and reliability are non-negotiable.

Key Features

  • 316 Stainless Steel: High resistance to saltwater, chemicals, and extreme environments.
  • Split Lock Function: Applies spring pressure to help resist fastener back-out.
  • Thermal and Dynamic Load Resistant: Withstands repeated movement and load cycles.
  • Engineered Fit: Designed for 1/2" stainless steel bolts and screws.

Common Applications

  • Dock and pier hardware
  • Food-grade equipment
  • Framing systems
  • HVAC support brackets
  • Industrial machinery mounts

Installation Tips

  • Pair with matching stainless hardware to avoid galvanic corrosion.
  • Do not fully flatten—tension is key to the locking action.

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.
