Manufactured from steel with a Bowma-Guard protective finish, this washer meets ASTM F436 standards and carries a Rockwell C38-42 hardness rating, making it suited for structural and heavy-duty fastening applications. The washer measures 1.25 inches inside diameter, 2.75 inches outside diameter, and 0.177 inches thick. It ships in a package quantity of 10. Licensed tradespeople and contractors working with large-diameter fasteners rely on this part for consistent load distribution and corrosion resistance in demanding installations.\u003c\/p\u003e\n\u003cp\u003eThis USS flat washer is used in construction, structural steel work, and industrial equipment assembly wherever 1-1\/8 inch fasteners require a broad bearing surface. The oversized outer diameter relative to the screw size is characteristic of USS-series washers, which are specified when load distribution across a larger surface area is required. Typical applications include steel framing connections, heavy equipment mounting, and anchor bolt installations. The Bowma-Guard finish provides a layer of corrosion protection suited to interior and sheltered exterior environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM F436 fastener standard compliance for structural applications\u003c\/li\u003e\n  \u003cli\u003eRockwell C38-42 hardness for reliable load-bearing performance\u003c\/li\u003e\n  \u003cli\u003eBowma-Guard protective finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eUSS series geometry with 2.75 inch OD for broad load distribution\u003c\/li\u003e\n  \u003cli\u003eMaterial Grade 9 steel construction\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 10 per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service USS flat washer for use with 1-1\/8 inch screw and bolt fasteners in structural and industrial fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed contractors, ironworkers, or maintenance technicians working with large-diameter fastener assemblies.
