The VALUE COLLECTION 88547997 is an SAE flat washer sized for 5/16 inch screws, manufactured from Grade 8 alloy steel. It measures 11/32 inches inner diameter, 11/16 inches outer diameter, and 1/16 inch thick. These dimensions follow SAE standards, providing a wider bearing surface than USS-pattern washers of the same screw size. Sold in a 125-piece package, this washer is suited for structural and mechanical fastening applications where higher-strength hardware is required. Grade 8 alloy steel offers greater hardness and tensile strength compared to low-carbon alternatives, making it appropriate for demanding assemblies in HVAC equipment mounting, electrical panel work, and general mechanical installations.
This washer is used wherever a 5/16 inch fastener requires load distribution across a mating surface. Common applications include equipment base mounting, bracket assembly, flange connections, and structural hardware in both residential and light commercial trade work. The SAE profile is the standard choice when a moderate-diameter bearing surface is needed without the extra spread of a fender washer. Installers across HVAC, plumbing, and electrical trades keep Grade 8 SAE flat washers on hand for general fastening tasks involving bolts, cap screws, and hex fasteners in this size range.
Designed for use with 5/16 inch SAE fasteners including hex bolts, cap screws, and machine screws in standard inch-system assemblies.
Install using standard hand tools or a wrench appropriate for the mating fastener. Ensure the washer seats flat against the bearing surface before torquing the fastener. Grade 8 hardware should be paired with fasteners of equivalent or greater grade to avoid mismatched load ratings. Power down or de-energize any equipment before performing fastener work on live mechanical or electrical assemblies.
