Monster Overview
Fix your project right the first time with USS Flat Washers – Medium Carbon Thru-Hardened, Plain Finish from Monster Bolts. These USA-made USS pattern washers feature a larger outside diameter than SAE washers, making them ideal for construction, general fabrication, machinery repair, and heavy-duty industrial applications.
Built from medium carbon thru-hardened steel, these washers provide a strong, consistent load-bearing surface under nuts and bolt heads. The plain (uncoated) finish is suitable for indoor or controlled environments, or for assemblies that will be painted, plated, or otherwise treated after installation.
