The GIBRALTAR Z9188-BEV-SS is a beveled round flat washer manufactured from Grade 18-8 stainless steel, designed for use with 7/8 inch screws. The beveled profile distributes load evenly across angled or tapered mating surfaces, reducing stress concentration at the fastener seat. With an inside diameter of 0.906 inches, an outside diameter of 1.75 inches, and a thickness of 0.25 inches, this washer is sized for structural and mechanical fastening applications where corrosion resistance and dimensional consistency are required. Licensed trades and maintenance professionals use this type of washer in plumbing, HVAC, and mechanical piping assemblies.
This washer is suited for both residential and light commercial applications where fasteners pass through angled flanges, I-beams, or sloped bearing surfaces. The beveled geometry compensates for surface irregularities that a standard flat washer cannot accommodate. It is commonly installed in pipe hanger systems, structural brackets, equipment mounting, and anywhere a tapered bearing surface demands a matching washer profile.
Designed as an OEM-style replacement or direct-use beveled flat washer for 7/8 inch screw and bolt fastener assemblies in mechanical, plumbing, and structural applications.
Install using standard hand and power tools appropriate for the fastener size. Ensure the beveled face is oriented to match the taper of the mating surface before torquing. Shut down and de-energize any equipment before accessing fastener assemblies in live systems. Follow applicable mechanical and structural codes for fastener torque and assembly requirements.
