Brighton Best 5/16" USS Zinc Steel Flat Washer - 100 Qty

Brighton Best 5/16 USS Zinc Flat Washer 31NWUS0Z is a 5/16 USS zinc flat washer designed for load distribution and surface protection in bolted assemblies. The product is classified as a flat washer used to provide a bearing surface under bolt heads and nuts in general fastening applications. The washer is manufactured from carbon steel to support standard mechanical loads in structural and equipment fastening. The zinc-plated finish provides corrosion resistance for interior and light exterior environments. Installation is performed by placing the washer over the bolt shank prior to nut installation. The flat profile supports even load distribution and reduces surface damage during torque application. The washer is compatible with bolts and nuts in concrete anchoring hardware, steel fabrication, and equipment mounting. The product supports use by contractors, fabricators, and maintenance professionals. The pack contains 100 units for jobsite and bulk inventory use.

Zinc plating supports resistance to oxidation in dry and light moisture environments.

USS sizing supports compatibility with common 5/16 fasteners used in industrial and maintenance assemblies.

Limits surface indentation on softer substrates under clamping load during tightening operations.
