Description

Conquest USS Flat Washers made from 18-8 stainless steel are built to perform in demanding environments. These washers provide a smooth, broad bearing surface that distributes load evenly across fastened materials. Whether you’re working with wood, metal, or composite, they help reduce the risk of surface damage and improve the integrity of your fastening job.

Made from high-grade 18-8 stainless steel, these washers deliver corrosion resistance and long-term durability. Ideal for marine, outdoor, and industrial applications, they’re a go-to solution for pros and DIYers alike. These washers are compatible with a wide range of bolt sizes and are available in multiple diameters to suit your specific needs.

Each washer is engineered with a precision-machined inner diameter to ensure a snug fit around the bolt shaft. Installation is straightforward, just slide the washer onto the bolt or screw before threading into place. Their flat design ensures a clean fit and helps prevent pull-through or distortion on softer surfaces.

Features:

  • 18-8 Stainless Steel: Delivers corrosion resistance and strength for outdoor and marine use.
  • USS Pattern: Offers a wider inner diameter than SAE washers for broad load distribution.
  • Versatile Sizing: Available in a range of diameters to match a variety of bolt sizes.
  • Easy Installation: Simply place under the bolt head or nut to improve load-bearing performance.
  • Protects Materials: Helps prevent damage to surfaces and extends fastener life.

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.
