Description

7/8" Conquest USS Flat Washer – 316 Stainless Steel

This 7/8" USS flat washer offers long-lasting performance in large-scale marine, outdoor, and industrial installations. Its 316 stainless build ensures corrosion resistance where others fail. The USS size helps distribute bolt force to protect structural surfaces. A must-have for 7/8" coarse-thread stainless bolts and nuts.

Ensure fasteners and washers share the same material and finish for proper fit and corrosion resistance.

7/8" Stainless USS Washer for Marine and Utility Bolt Reinforcement

This washer is ideal for bridge connections, pier assembly, or exposed utility mounting. Its thickness and wide surface prevent fastener embedment into wood or metal. Stands up to harsh environments while maintaining joint integrity. Common in saltwater, agriculture, and chemical processing jobs.

Key Features

  • 316 Stainless: Marine and chemical resistance built in.
  • USS Pattern: Maximizes surface load spreading.
  • Precision Machined: Designed for coarse-thread bolts.
  • Corrosion-Proof: Won’t degrade over time in wet conditions.
  • Heavy-Duty Fit: Reinforces large-bolt connections.

Common Applications

  • Seawall bolt anchoring
  • Chemical equipment builds
  • Outdoor railing systems
  • Bridge joint hardware
  • Utility structure framing

Installation Tips

  • Use with matching nuts and bolts made from 316 stainless steel.
  • Position washer flat under the nut or bolt head.
  • Torque fasteners evenly for maximum seal and load distribution.

Quality parts - good price

Needed some stainless steel fasteners for my gate refresh and the local stores didnt have the correct size and would have been more costly.

Excellent!

I purchased a few 7" SS bolts, nuts and washers for them for my boat. The order total was minimal and it was online and my first time using Fasteners Plus, so I wasn't sure when or if I would get them. However.....there were constant email updates from order acceptance to delivery and everything came well packaged and in good form. If my experience is indicative of their usual service, they are top notch and I run an aerospace fastener business for a living.
