Gibraltar Z9189-BEV-H Beveled Round Flat Washer 1 in

Product Description

The GIBRALTAR Z9189-BEV-H is a beveled round flat washer machined from case-hardened 12L14 steel with a plain finish. Designed for 1-inch screw sizes, it features a 1-1/32-inch inside diameter and a 2-inch outside diameter, with a thickness of 5/16 inches. The beveled seating surface distributes clamping load evenly under fastener heads or nuts, reducing surface damage and improving joint integrity. This washer is suited for structural and mechanical fastening applications where hardened bearing surfaces are required. Installation is handled by maintenance technicians, millwrights, and trade professionals working with heavy fastening assemblies.

This washer is used in industrial, commercial, and trade applications requiring a hardened load-bearing surface beneath a 1-inch fastener. The beveled geometry accommodates angled or countersunk mating surfaces, making it common in structural steel connections, equipment mounting, and heavy mechanical assemblies. The plain finish is appropriate for interior or dry-environment use where corrosion resistance is not a primary requirement. Sold individually, with a minimum order quantity of 5 pieces.

Key Features

• Beveled round profile distributes load evenly under fastener heads and nuts
• Case-hardened 12L14 steel construction resists deformation under high clamping force
• 1-1/32-inch inside diameter sized for 1-inch screws and bolts
• 2-inch outside diameter provides broad load-bearing surface area
• 5/16-inch thickness adds rigidity for demanding fastening applications
• Plain finish suitable for dry or protected indoor installations

Compatibility

Designed for use with 1-inch screw and bolt fasteners in structural, mechanical, and equipment fastening assemblies requiring a beveled hardened washer seat.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or trade professionals using standard hand and power tools. Ensure the mating surface is clean and free of debris before seating the washer. The beveled face should be oriented toward the angled or countersunk surface as required by the joint design. Follow applicable torque and fastening specifications provided by the equipment or structural engineer of record.
