Hillman Fasteners 280060 Sae Flat Washer 3/8 in Zinc 100 Pack

Product Description

The HILLMAN FASTENERS 280060 is a 3/8-inch SAE flat washer supplied in a 100-piece pack. Flat washers distribute load across a fastener's bearing surface, reducing the risk of pull-through and surface damage on bolted assemblies. This washer is manufactured from zinc-plated steel, which provides baseline corrosion resistance suitable for general-purpose mechanical and structural applications. The SAE designation indicates the washer meets Society of Automotive Engineers dimensional standards, making it a consistent, predictable fit for standard 3/8-inch fastener hardware. Plumbers, electricians, HVAC technicians, and general contractors commonly keep this size on hand for equipment mounting, pipe support bracketing, and panel attachment work.

This washer is used across residential and light commercial trade applications wherever a 3/8-inch bolt or threaded rod requires a bearing surface. Common install scenarios include equipment pad anchoring, ductwork hanger assemblies, electrical panel mounting, and plumbing fixture support. The 100-piece pack quantity suits service van stock and job-site use where multiple fastening points are involved.

Key Features

• SAE flat washer dimensional standard for consistent fit on 3/8-inch fasteners
• Zinc-plated steel construction for corrosion resistance in general-purpose use
• 100-piece pack suitable for job-site stocking and repetitive fastening tasks
• Load-distributing geometry reduces pull-through and surface marring on assembled components

Compatibility

Designed as a standard SAE flat washer for use with 3/8-inch bolts, screws, and threaded rod in general mechanical and trade assembly applications.

Installation Notes

Flat washers are installed by any trade technician performing bolted assembly work. Always power down or de-energize equipment before accessing fastened panels or enclosures. Verify washer material compatibility with the installation environment, as zinc-plated steel may not be appropriate for high-moisture or corrosive exposure without additional protection. Follow applicable codes such as NEC or IPC where fastener specifications are governed by installation standards.
