Gibraltar Z9182-BEV Beveled Round Flat Washer 5/16 in

Product Description

The GIBRALTAR Z9182-BEV is a beveled round flat washer designed for use with 5/16-inch screws and fasteners. Manufactured from 12L14 steel with a plain finish, this washer distributes load across a bearing surface while providing the angled seating surface characteristic of beveled washer designs. With an inside diameter of 11/32 inches, an outside diameter of 3/4 inches, and a thickness of 1/8 inch, it fits standard 5/16-inch fastener assemblies in structural and mechanical applications. Installation is performed by maintenance technicians, pipefitters, millwrights, and general tradespeople across a wide range of fastening tasks.

This washer is suited for use in both residential and light commercial mechanical assemblies where a beveled bearing surface is required between a fastener head or nut and a workpiece. Typical applications include equipment mounting, structural connections, and general mechanical fastening where load distribution and a flush or angled seat are needed. The plain finish makes it appropriate for indoor or protected installations where corrosion resistance is not a primary requirement.

Installation Notes

Install by placing the washer over the fastener shank between the fastener head or nut and the mating surface, with the beveled face oriented toward the fastener bearing surface as required by the assembly design. Ensure the fastener and washer material are compatible with the application environment to prevent galvanic corrosion. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the fastener being used.
