Gibraltar Z9187-BEV-SS Beveled Round Flat Washer 3/4 in Ss

Product Description

The GIBRALTAR Z9187-BEV-SS is a beveled round flat washer machined from Grade 18-8 stainless steel, designed for use with 3/4 inch fasteners. The beveled profile provides a tapered bearing surface that compensates for slight angular misalignment between mating surfaces, distributing clamp load more evenly than a standard flat washer. With an inside diameter of 0.781 inches, an outside diameter of 1.500 inches, and a thickness of 0.250 inches, this washer meets common inch-series dimensional standards. The 18-8 stainless steel construction delivers corrosion resistance suited to wet, outdoor, and chemically active environments. Plumbers, pipefitters, HVAC mechanics, and general tradespeople reach for this washer in bolted assemblies where surface alignment or environmental exposure is a factor.

This washer is appropriate for use in residential and commercial mechanical installations involving 3/4 inch fastener assemblies. Typical applications include pipe flange bolting, equipment mounting, structural bracketing, and any bolted joint where a beveled bearing surface improves load distribution. The stainless steel grade makes it a practical choice in plumbing, pool equipment, and outdoor HVAC installations where mild steel hardware would corrode prematurely.

Key Features

• Beveled round profile compensates for angular misalignment at the bearing surface
• Grade 18-8 stainless steel construction resists corrosion in wet and outdoor service
• Inside diameter of 0.781 inches fits standard 3/4 inch fasteners with controlled clearance
• Outside diameter of 1.500 inches provides broad load distribution across mating surfaces
• Thickness of 0.250 inches delivers consistent standoff and clamp load characteristics
• Inch-series dimensions compatible with standard inch-system fastener assemblies

Compatibility

Designed for use with 3/4 inch screw and bolt fasteners in inch-series bolted assemblies requiring a beveled round flat washer.

Installation Notes

Installation is typically performed by plumbers, pipefitters, HVAC mechanics, or electricians as part of a bolted assembly. Ensure mating surfaces are clean and free of debris before seating the washer to maintain proper clamp load. The beveled face should be oriented toward the tapered or irregular surface to achieve the intended load distribution. Follow applicable codes such as the IPC or IFGC for pipe flange fastener requirements relevant to the system being serviced.
