Gibraltar 42614G Standard Flat Washer Size 8 Black Oxide

Product Description

The GIBRALTAR 42614G is a standard flat washer designed for use with size 8 screws in general mechanical and structural fastening applications. Manufactured from 1010 case-hardened steel with a black oxide finish, this washer provides reliable load distribution and surface protection in demanding environments. The black oxide coating offers mild corrosion resistance and reduces light reflection on exposed fasteners. With an inside diameter of 3/16 inches, an outside diameter of 7/16 inches, and a thickness of 5/64 inches, the 42614G meets standard inch-series flat washer dimensions. Maintenance technicians, electricians, plumbers, and general tradespeople install this type of washer across a wide range of fastening tasks.

The 42614G is suited for residential and light commercial applications where a size 8 fastener requires a bearing surface to distribute clamp load and prevent pull-through. Typical uses include equipment panels, junction boxes, mechanical enclosures, and general hardware assembly. The case-hardened steel construction withstands deformation under fastener load, making it appropriate for applications where softer washers would compress or deform over time.

Key Features

• Case-hardened 1010 steel construction resists deformation under clamp load
• Black oxide finish provides mild corrosion resistance and low-reflectivity appearance
• Inside diameter of 3/16 inches fits size 8 screws
• Outside diameter of 7/16 inches distributes load across a broad bearing surface
• Thickness of 5/64 inches meets standard inch-series flat washer geometry
• Inch system of measurement for compatibility with standard imperial fasteners

Compatibility

Designed as an OEM-style replacement or standard hardware component for use with size 8 imperial screws in inch-series fastening assemblies.

Installation Notes

Install using hand tools standard to the applicable trade; ensure the washer seats flat against the mating surface before torquing the fastener. Power down or de-energize any equipment before servicing fastened assemblies in electrical or mechanical enclosures. Follow applicable codes such as the NEC for electrical installations or the IPC for plumbing applications when washers are used in those systems.
