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

Product Description

The GIBRALTAR Z9183-BEV-H is a beveled round flat washer designed for 3/8 inch screw applications. Manufactured from case-hardened 12L14 steel with a plain finish, this washer distributes fastener load across a wider bearing surface while accommodating angled or uneven mating surfaces with its beveled profile. The inside diameter measures 13/32 inches (0.4063 inches) and the outside diameter measures 7/8 inches (0.8750 inches), with a thickness of 1/8 inch (0.1250 inches). It is suited for trade and industrial fastener assemblies where surface hardness and dimensional consistency are required.

This washer is used in mechanical assembly, structural fastening, and equipment installation across HVAC, plumbing, electrical, and general construction trades. The beveled design makes it appropriate for applications where fastener heads or nuts must seat against angled flanges or tapered surfaces. It is sold individually with a minimum order quantity of 25 units, making it practical for service stock and job-site supply.

Installation Notes

Installation is performed by qualified tradespeople during mechanical assembly or equipment fastening. Power down or isolate the relevant system before disassembling fastened joints in live equipment. Ensure the beveled face is oriented toward the angled or tapered surface to achieve proper seating. Follow applicable mechanical and structural codes for fastener torque and assembly procedures.
