Value Collection FWSIS1370-025BX Sae Flat Washer 25 Pack

Product Description

The VALUE COLLECTION FWSIS1370-025BX is a zinc-plated steel SAE flat washer designed for 1-3/8 inch screw sizes. It features a 1-7/16 inch inside diameter, a 2-3/4 inch outside diameter, and a thickness of 5/32 inches. The zinc plating provides corrosion resistance in exposed or mildly harsh environments. This washer meets SAE dimensional standards, making it suitable for mechanical assemblies, structural connections, and general fastening applications across trades including plumbing, HVAC, and electrical installation. Sold in a minimum order quantity of 25 pieces.

SAE flat washers like the FWSIS1370-025BX are used wherever load distribution under a bolt head or nut is needed. They are common in equipment mounting, pipe support brackets, sheet metal assemblies, and structural connections. The SAE specification results in a larger outer diameter relative to screw size compared to USS standards, distributing clamping force over a wider bearing surface. Suitable for residential and commercial trade applications where a 1-3/8 inch fastener is used.

Key Features

• SAE flat washer profile with larger OD for improved load distribution
• Steel construction for strength in mechanical and structural fastening
• Zinc-plated finish for corrosion resistance in typical service environments
• 1-7/16 inch inside diameter fits 1-3/8 inch screw size with standard clearance
• 2-3/4 inch outside diameter spreads clamping load across a wide bearing surface

Compatibility

Designed for use with 1-3/8 inch screws and bolts conforming to SAE flat washer dimensional standards in inch-measurement fastening systems.

Installation Notes

Install using standard hand tools appropriate for the bolt or screw size. Ensure the washer seats flat against the mating surface before torquing the fastener. Power down or de-energize any equipment before servicing fastened assemblies in electrical or mechanical systems. Follow applicable NEC, IPC, or IFGC guidelines as appropriate to the installation trade.
