Description

5/16" Conquest USS Flat Washer - Hot Dip Galvanized

Engineered for high-load support, the 5/16" USS flat washer features a hot dip galvanized finish to guard against corrosion. Designed for structural and outdoor use, it spreads load to minimize material damage. This washer fits coarse-thread bolts, helping reinforce joints and prevent fastener pull-through. Ideal for both marine and construction settings.

Always confirm washer and bolt compatibility prior to installation for optimal load distribution.

Great service

The exact size washer I needed in a quantity I needed that no other business seemed to have. Very good price, even with delivery charges, that big box stores by almost 75%. That and the quick delivery means I can go to fasteners+ for future needs and not have to shop around for the best deal.
