Value Collection FWI5150-005BX Structural Flat Washer

Product Description

The VALUE COLLECTION FWI5150-005BX is a structural flat washer designed for use with 1-1/2 inch screws and bolts in heavy-duty fastening applications. Manufactured from steel to material grade 1035/1050 with a plain finish, this washer meets ASTM F436 standards for structural applications. It features an inside diameter of 1-5/8 inches and an outside diameter of 3 inches, providing a wide bearing surface that distributes load across the mated material. Licensed tradespeople and structural assembly crews rely on washers like this one to prevent fastener pull-through and surface damage in high-load connections.

This structural flat washer is suited for steel-to-steel connections, wood-to-steel interfaces, and general structural bolting work in commercial and industrial construction, as well as heavy mechanical assemblies. Its ASTM F436 compliance makes it appropriate for structural steel applications where verified material and dimensional standards are required. The plain finish is suitable for interior applications or where additional corrosion protection will be applied separately.

Installation Notes

Structural flat washers of this type are typically installed by ironworkers, millwrights, or general contractors following applicable structural codes. Always ensure mating fasteners and nuts are rated for the intended load before assembly. Inspect washers for burrs or deformation before use. Follow project specifications and applicable building codes for torque and assembly requirements.
