Gibraltar Z9189-BEV-SS Beveled Round Flat Washer 1 in Ss

Product Description

The GIBRALTAR Z9189-BEV-SS is a beveled round flat washer designed for 1 inch screw applications. Machined from Grade 18-8 stainless steel, this washer provides corrosion resistance in wet, outdoor, and chemically exposed environments. The beveled profile seats flush against angled or countersunk surfaces, distributing clamp load evenly and reducing fastener stress. With an inside diameter of 1.0313 inches, an outside diameter of 2 inches, and a thickness of 0.3125 inches, this washer suits structural and mechanical assemblies where dimensional precision matters. Licensed tradespeople and industrial maintenance technicians use this type of hardware in plumbing, HVAC mounting, and general mechanical installations.

This washer is suited for residential and commercial fastening applications requiring a beveled seating surface under bolt heads or nuts. Typical use cases include pipe flange assemblies, equipment mounting, and structural connections where standard flat washers do not provide adequate load distribution on angled surfaces. The 18-8 stainless steel construction makes it appropriate for both indoor and outdoor service, including humid or corrosive environments common in HVAC and plumbing trades.
