Product Description

The VALUE COLLECTION A997400 is a Grade 316 stainless steel SAE flat washer sized for 1-1/4 inch screws and bolts. With an inside diameter of 1-5/16 inches, an outside diameter of 2-1/2 inches, and a thickness of 0.1562 inches, this washer meets SAE dimensional standards for load distribution and surface protection. Grade 316 stainless steel provides strong resistance to corrosion and oxidation, making it well suited for harsh or wet environments. Licensed tradespeople and experienced maintenance professionals install these washers as part of bolted connections across a wide range of commercial and industrial assemblies.

This washer is used wherever a 1-1/4 inch fastener requires an SAE-specification flat washer to spread clamp load and protect the mating surface. Typical applications include plumbing and mechanical equipment mounting, structural connections in corrosive environments, marine and coastal installations, and chemical processing facilities where 316 stainless is specified for its molybdenum-enhanced corrosion resistance. Sold in a package of 5 to support small-quantity service and repair work.
