Product Description

The VALUE COLLECTION FWI5112-010BX is a structural flat washer designed for use with 1-1/8 inch screws and bolts in heavy-duty fastening applications. Manufactured from steel with a plain finish, this washer meets ASTM F436 standards for structural fasteners. It features a 1-1/4 inch inside diameter and a 2-1/4 inch outside diameter, providing the broad bearing surface required to distribute load across structural connections. Licensed tradespeople and construction professionals working on steel-to-steel or steel-to-concrete assemblies will find this washer suited to code-compliant structural work. Each package contains one washer with a minimum order quantity of 10 pieces.

This washer is used in structural steel construction, steel framing, heavy timber connections, and similar applications where ASTM F436 compliance is required.

Installation Notes

Installation should be performed by qualified ironworkers, structural mechanics, or licensed contractors in accordance with applicable building codes and project specifications. Shut down or de-energize any adjacent systems before working in confined structural bays. Torque fastener assemblies to project-specified values using calibrated torque wrenches — do not rely on feel alone for structural connections. Inspect washers for burrs or deformation before installation to ensure proper seating and load transfer.
