Value Collection FWSI81371-025BX Sae Flat Washer 1-3/8 in

Product Description

The VALUE COLLECTION FWSI81371-025BX is a Grade 8 steel SAE flat washer designed for use with 1-3/8 inch screws. It features a zinc yellow dichromate finish that provides corrosion resistance in demanding environments. The washer meets ASME B18.21.1 standards and is manufactured to SAE dimensional specifications, with a 1-7/16 inch inner diameter, 2-3/4 inch outer diameter, and 5/32 inch thickness. This washer is a standard hardware component installed by licensed tradespeople and contractors across HVAC, plumbing, electrical, and structural applications wherever a load-distributing fastener interface is required.

This SAE flat washer is suited for residential and commercial construction, mechanical equipment installations, and utility system assembly. Its larger outer diameter relative to the screw size distributes clamp load across a wider surface area, reducing the risk of fastener pull-through in softer base materials. It is commonly used in structural connections, equipment mounting, and panel attachment. The minimum order quantity is 25 pieces, making it appropriate for job-site stock or service truck inventory replenishment.
