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.

Bat House Latch

All of the hardware we use is 316 Marine Grade Stainless Steel. Our bird homes and bat houses are exposed to the elements 24-7 year round. Some are placed on coastal properties where salt air is hard on metals. We bought and have previously bought some of our supplies from these folks. They’ve always been friendly and professional with us.

Great service

All items arrived in good condition and as promised - with the exception of one through-bolt which had "escaped" the packaging (through a hole in the cardboard box). I called customer service and they shipped out a replacement the same day and we received it (well packaged) in no time, so without impact on our timeline. Definitely an easy and no hassle experience.
