Gibraltar Z9207BR Extra Thick Flat Washer Brass 7/8 in

Product Description

The GIBRALTAR Z9207BR is an extra thick flat washer machined from brass with a plain finish, designed for use with 7/8 inch screws. It features an inside diameter of 29/32 inches (0.9062 inches), an outside diameter of 1-3/4 inches (1.7500 inches), and a thickness of 1/4 inch (0.2500 inches). The increased thickness over a standard flat washer provides added load distribution and resistance to compression, making it suitable for applications where a standard washer would deform or seat too deeply. Brass construction resists corrosion in wet or chemically active environments. Plumbers, electricians, and general mechanical tradespeople install this type of washer across a range of fastening applications.

This washer is appropriate for residential and commercial fastening applications where a 7/8 inch fastener requires broad load distribution and extra bearing surface. Typical uses include pipe flange connections, equipment mounting, and structural assemblies where brass is specified for corrosion resistance or to avoid galvanic incompatibility with dissimilar metals. The plain finish leaves the brass surface uncoated, suitable for applications where additional plating is not required or where the installer will apply a sealant or coating in the field.
