Value Collection 99741 Sae Flat Washer 5/16 in Steel

Product Description

The VALUE COLLECTION 99741 is a standard SAE flat washer designed for use with 5/16 inch screws and bolts. Manufactured from Grade 8 steel with a plain finish, this washer distributes load evenly across a fastened joint, reducing surface damage and preventing pull-through on softer substrates. The inside diameter measures 11/32 inches and the outside diameter measures 11/16 inches. These washers are used throughout mechanical assembly, structural fastening, and general maintenance applications across a wide range of trades including HVAC, plumbing, electrical, and general construction.

This washer is suited for residential and commercial fastening applications wherever a 5/16 inch fastener requires a bearing surface. The SAE dimensional standard makes it compatible with close-tolerance assemblies where a narrower OD profile is required compared to USS-spec washers. Typical use cases include equipment mounting, panel assembly, pipe hanger installation, and structural bracketing. Grade 8 steel construction provides the strength needed for demanding mechanical environments.

Key Features

• SAE flat washer standard — narrower OD profile for close-tolerance assemblies
• Grade 8 steel construction for high-strength fastening applications
• Plain finish suitable for interior and dry-environment applications
• Inside diameter of 11/32 inches fits 5/16 inch screws and bolts
• Outside diameter of 11/16 inches for effective load distribution

Compatibility

Designed for use with 5/16 inch SAE-standard screws and bolts in general mechanical, structural, and maintenance fastening applications.

Installation Notes

Installation does not require specialized trade licensing but is a standard task performed by mechanics, electricians, HVAC technicians, and plumbers during equipment assembly or structural fastening. Always ensure the washer is seated flat against the mating surface before torquing the fastener. Plain-finish steel washers are best suited for interior or protected environments where corrosion exposure is minimal.
