Gibraltar 42610G Standard Flat Washer 1-1/8 Inch

Product Description

The GIBRALTAR 42610G is a standard flat washer designed for use with 1-1/8 inch screws and fasteners. Manufactured from case-hardened 1010 steel with a black oxide finish, it provides load distribution and surface protection in demanding mechanical and structural assemblies. The washer measures 1-5/32 inches inner diameter, 2-1/4 inches outer diameter, and 7/32 inches thick. The black oxide coating offers mild corrosion resistance and a low-reflectance appearance suitable for industrial environments. Weighing approximately 0.05 pounds, this washer follows inch measurement standards and is sold as a single unit. It is appropriate for trade and maintenance applications where a durable, case-hardened fastener component is required.

This washer is used in mechanical, structural, and maintenance assemblies where a standard flat washer profile is needed for 1-1/8 inch screw or bolt applications. Typical uses include equipment mounting, structural connections, and general fastening tasks in commercial and industrial settings. Licensed tradespeople and maintenance professionals working with heavy fastener assemblies will find this washer fits standard inch-system hardware configurations. Its case-hardened construction makes it suitable for higher-load applications where a softer washer would deform under torque.
