Gibraltar Z9183-BEV-SS Beveled Round Flat Washer 3/8 in

Product Description

The GIBRALTAR Z9183-BEV-SS is a beveled round flat washer designed for 3/8-inch screw applications. Manufactured from Grade 18-8 stainless steel, it provides reliable corrosion resistance in demanding environments. The beveled profile allows the washer to seat flush against tapered or angled surfaces, distributing load evenly and reducing stress on fastened assemblies. With an inside diameter of 0.4063 inches, an outside diameter of 0.8750 inches, and a thickness of 0.1250 inches, this washer meets standard inch-system dimensional requirements. Licensed tradespeople and maintenance technicians working in HVAC, plumbing, and general mechanical applications will find this washer suitable for a wide range of fastening tasks.

This washer is suited for use in residential and light commercial mechanical assemblies where corrosion resistance and dimensional accuracy are required. It is commonly installed in equipment panels, pipe supports, electrical enclosures, and structural connections where a 3/8-inch fastener is used. The 18-8 stainless steel construction makes it appropriate for wet or humid environments such as those found in plumbing chases, HVAC equipment rooms, and outdoor mechanical installations.

Compatibility

Designed as an OEM-style replacement or standard-fitment washer for assemblies using 3/8-inch inch-system fasteners where a beveled round flat washer is specified.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or electricians as part of equipment assembly or field repair. De-energize all electrical circuits and shut off fluid supply lines before disassembling any fastened joint. Use appropriately sized hand tools or torque wrenches rated for the fastener grade and application. Avoid mixing stainless steel fasteners with dissimilar metals in environments where galvanic corrosion is a concern.
