1/4" Conquest USS Flat Washer – 316 Stainless Steel

This 1/4" USS washer made from 316 stainless steel provides maximum corrosion resistance in small-scale fastener assemblies. It's built to withstand coastal, chemical, or wet environments with confidence. The USS pattern delivers a broad bearing surface to distribute load and protect material. Compatible with 1/4" coarse-thread stainless bolts and nuts.

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

1/4" Stainless USS Washer for Marine & Outdoor Fastening

This washer is perfect for marine-grade hardware, chemical exposure points, or outdoor decking with stainless bolts. Its oversized profile helps reduce distortion and wear during installation.

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.
