Value Collection FWI5100-010BX Structural Flat Washer

Product Description

The VALUE COLLECTION FWI5100-010BX is a structural flat washer designed for use with 1-inch fasteners in heavy-duty bolted connections. Manufactured from steel to material grade 1035/1050, it meets ASTM F436 standards for structural applications. The washer features a 1-1/8 inch inside diameter and a 2-inch outside diameter, providing a broad bearing surface that distributes clamping load across the joint. The plain finish leaves the steel uncoated, making it suitable for applications where a secondary coating or treatment will be applied on site. Trade professionals rely on this washer for structural steel connections in construction, mechanical assemblies, and industrial installations.

This washer is used in structural bolting applications where ASTM F436 compliance is required. Typical installations include steel-to-steel connections in building frames, bridgework, and heavy equipment mounting. It is sized for 1-inch fastener systems and is appropriate for use with heavy hex bolts and high-strength structural fasteners common in commercial and industrial construction. Licensed ironworkers, millwrights, and general contractors working to structural codes frequently specify this washer for bolted joint assemblies.

Installation Notes

Installation should be performed by qualified tradespeople following applicable structural codes and project specifications. Always verify that mating fasteners and bolt hole dimensions match the washer inside diameter before torquing.
