Description

The Conquest Split Lock Washer – 316 Stainless Steel is engineered to deliver steadfast tension and vibration resistance in critical fastening applications. Designed to work with a variety of fasteners, this washer ensures your hardware stays tight, even in the harshest environments.

Forged from premium 316 stainless steel, this split lock washer offers superior corrosion resistance compared to standard alloys, making it a top choice for marine, industrial, and outdoor construction projects. Its split-ring design creates spring tension under the fastener head, helping to prevent loosening caused by vibration or dynamic loads.

Whether you're working in saltwater exposure, chemical processing plants, or high-humidity zones, this washer provides a simple yet effective safeguard against joint failure. It’s ideal for mechanical assemblies, HVAC systems, electrical enclosures, and other projects that demand reliability and long-term performance.

Key Features:

  • 316 Stainless Steel: Provides top-tier corrosion resistance in harsh or marine environments.
  • Split-Ring Design: Maintains tension and resists loosening due to vibration.
  • Reliable Performance: Withstands thermal expansion, dynamic loads, and heavy-duty applications.
  • Multiple Sizes Available: Choose the diameter and thickness that suits your project.
  • Compatible Hardware: Works with bolts, screws, and other threaded fasteners.

Common Applications:

  • Marine equipment and dock hardware
  • Industrial piping and machinery
  • Electrical enclosures and HVAC systems
  • Food processing and chemical facilities
  • Outdoor structural assemblies

Installation:

Place the split lock washer between the fastener head and the mounting surface. Tighten until the washer flattens slightly—this tension helps prevent loosening. Use with compatible stainless steel fasteners to maintain corrosion resistance across the entire assembly.

Hi quality 316

Don Cordell Ward
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.
