Value Collection 31446 Sae Flat Washer 3/8 in Steel Zinc

Product Description

The VALUE COLLECTION 31446 is a standard SAE flat washer designed for use with 3/8-inch screws and bolts. Manufactured from steel with a zinc-plated finish, this washer distributes fastener load across a wider surface area, reducing the risk of pull-through and surface damage. The 13/32-inch inner diameter fits cleanly over 3/8-inch fastener shanks, while the 13/16-inch outer diameter provides consistent bearing surface coverage. At 1/16 inch thick, it meets standard SAE dimensional specifications. This washer is suitable for general mechanical assembly, structural connections, and equipment maintenance tasks across a broad range of trades.

This flat washer is used in residential and commercial construction, HVAC equipment assembly, plumbing fixture mounting, electrical panel and conduit support work, and general mechanical maintenance. Its SAE profile suits applications where a moderate outer diameter and precise fit are required. Licensed tradespeople and maintenance technicians commonly stock this washer for routine fastener assembly and repair work across multiple system types.
