Value Collection 88547989 Sae Flat Washer 1/4 in Grade 8

Product Description

The VALUE COLLECTION 88547989 is an SAE flat washer sized for 1/4 inch screws, manufactured from Grade 8 alloy steel. It features a 9/32 inch inside diameter, 5/8 inch outside diameter, and 1/16 inch thickness. The SAE profile provides a wider bearing surface compared to USS washers, distributing clamp load across a larger area and reducing the chance of fastener pull-through. Grade 8 alloy steel delivers high tensile strength suitable for structural and heavy-duty mechanical assemblies. This washer ships in a package quantity of 125 pieces, making it practical for shop stock or project-specific fastener kits.

This washer is used in residential and commercial mechanical, plumbing, HVAC, and general construction applications where a 1/4 inch fastener requires a load-spreading seat. Common install scenarios include equipment mounting, ductwork and structural panel attachment, and general bolted assembly. The SAE dimension standard makes it compatible with standard 1/4 inch bolts and screws in inch-measurement fastener systems. Installed by HVAC technicians, plumbers, electricians, and general maintenance trades as part of routine assembly and repair work.

Key Features

• Grade 8 alloy steel construction for high tensile strength in demanding assemblies
• SAE flat washer profile with wider bearing surface to distribute clamp load
• 9/32 inch inside diameter fits standard 1/4 inch screws and bolts
• 5/8 inch outside diameter provides broad load-bearing contact area
• 1/16 inch thickness for a low-profile fit in tight clearance applications
• Inch measurement system for compatibility with standard SAE fastener sets

Compatibility

Designed as an SAE-standard flat washer for use with 1/4 inch screw and bolt fasteners in inch-measurement mechanical and construction assemblies.

Installation Notes

Install using standard hand tools; ensure the washer is seated flat against the mounting surface before torquing the fastener. Power down or de-energize any equipment before accessing fastened panels or components in electrical or HVAC applications. Follow applicable codes such as the NEC or IFGC for fastener requirements in trade-specific installations. Do not substitute a Grade 8 washer in applications specified for a softer or corrosion-resistant material grade without verifying engineering requirements.
