Value Collection 81923898 Sae Flat Washer 5/16 in Steel 50pk

Product Description

The VALUE COLLECTION 81923898 is a 5/16 inch SAE flat washer made from Grade 2 steel with a zinc-plated finish. SAE flat washers distribute load across bolted and screwed connections, reducing surface damage and preventing fastener pull-through. This washer measures 0.339 inches inner diameter, 0.709 inches outer diameter, and 0.080 inches thick. The zinc coating provides basic corrosion resistance for general indoor and light outdoor applications. Sold in a package of 50, this part suits maintenance, repair, and assembly work across HVAC, plumbing, electrical, and general mechanical trades.

These SAE flat washers are used wherever a 5/16 inch fastener requires a bearing surface. Common applications include equipment mounting, panel attachment, pipe hanger assemblies, and structural connections in both residential and light commercial settings. The SAE standard calls for a wider outer diameter relative to the screw size compared to USS washers, making this style preferable when load distribution over a larger area is needed. Suitable for use with 5/16 inch bolts, screws, and threaded rod in standard inch-measurement assemblies.

Installation Notes

Install with standard hand tools; no special equipment is required for flat washer placement. Position the washer concentric with the fastener before tightening to ensure even load distribution. Do not substitute SAE washers for applications that specify USS or hardened fender washers, as dimensional and strength requirements differ. Follow applicable codes and equipment manufacturer torque guidelines for the fastener being used.
