Gibraltar Z9191-BEV Beveled Round Flat Washer Steel

Product Description

The GIBRALTAR Z9191-BEV is a beveled round flat washer machined from 12L14 steel with a plain finish. It is designed for use with 1-1/4 inch screws and features a beveled bearing surface that provides a consistent load distribution under bolt heads and nuts. The inside diameter measures 1.281 inches, the outside diameter measures 2.25 inches, and the thickness is 0.3125 inches. Weighing 0.05 pounds, this washer is sized for structural and mechanical fastening applications where a beveled seating surface is required. Machinists, millwrights, pipefitters, and maintenance technicians are the typical end users.

This washer suits industrial and commercial fastening assemblies where a standard flat washer cannot provide the angled seating surface needed to mate with tapered flanges, structural steel joints, or angled mounting surfaces. The plain finish is suitable for dry interior environments or applications where a coating will be applied after assembly. It is sold individually and is compatible with standard 1-1/4 inch fastener hardware.

Compatibility

Designed as an OEM-style replacement or direct-fit washer for mechanical and structural assemblies using 1-1/4 inch fasteners that require a beveled seating surface.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using standard hand or power tools. Ensure mating surfaces are clean and free of debris before seating the washer. Torque fasteners according to the assembly engineering specification for the application. Do not use this washer in corrosive or wet environments without applying an appropriate protective coating.
