Gibraltar Z9190-BEV-SS Beveled Round Flat Washer 18-8 Ss

Product Description

The GIBRALTAR Z9190-BEV-SS is a beveled round flat washer manufactured from Grade 18-8 stainless steel. Designed for a 1-1/8 inch screw size, this washer features a 1-5/32 inch inside diameter, a 2-1/4 inch outside diameter, and a 5/16 inch thickness. The beveled seat profile provides even load distribution under fastener heads and nuts, making it suitable for structural and mechanical fastening applications where corrosion resistance and dimensional precision are required. Licensed tradespeople in plumbing, HVAC, and general mechanical construction regularly specify 18-8 stainless steel hardware for its resistance to oxidation in wet and chemically active environments.

This washer is suited for residential and light commercial mechanical assemblies where a beveled seating surface is needed to mate with countersunk fastener heads or angled bearing surfaces. It is commonly used in piping support hardware, equipment mounting, and structural fastening installations exposed to moisture or mild corrosives. The 18-8 stainless steel construction meets common industry requirements for corrosion-resistant fastener hardware across plumbing, HVAC, and pool service environments.

Key Features

• Beveled round washer profile for uniform load distribution under fastener heads
• Grade 18-8 stainless steel construction for corrosion resistance in wet and chemically active environments
• 1-1/8 inch screw size with 1.1563 inch inside diameter for precise fastener fit
• 2.2500 inch outside diameter provides broad bearing surface coverage
• 0.3125 inch thickness delivers consistent dimensional stability under load

Compatibility

Designed as an OEM-style replacement or standard hardware component for 1-1/8 inch fastener assemblies requiring a beveled round washer with an 18-8 stainless steel material grade.

Installation Notes

This washer is installed by mechanics, plumbers, HVAC technicians, and general tradespeople as part of bolted or screwed assemblies. Ensure the fastener and mating surface are clean and free of debris before seating the washer. The beveled face should be oriented to match the countersunk or angled bearing surface of the fastener head or nut. Follow applicable mechanical and structural codes for fastener torque and assembly requirements.
