Value Collection FWI5037-100BX Structural Flat Washer 3/8 in

Product Description

The VALUE COLLECTION FWI5037-100BX is a structural flat washer designed for use with 3/8-inch fasteners in load-bearing and heavy-duty bolted connections. Manufactured from steel with a plain finish, this washer meets ASTM F436 standards, making it appropriate for structural steel applications where consistent clamping force distribution is required. The 13/32-inch inside diameter accommodates standard 3/8-inch bolt shanks with proper clearance, while the 13/16-inch outside diameter spreads load across a wide bearing surface. Installation is performed by ironworkers, structural mechanics, and general contractors working on steel-frame construction, machinery, and heavy assemblies.

This washer is suited for structural bolted connections in both commercial and industrial settings. Common applications include steel beam and column connections, baseplate installations, machinery mounting, and any bolted joint requiring compliance with ASTM F436. The plain steel finish is appropriate for dry or protected environments. Sold in a minimum order quantity of 100 units per order, making it practical for job-site and shop use where volume fastener supply is needed.

Installation Notes

Structural flat washers are installed by qualified ironworkers or mechanical contractors as part of bolted structural assemblies. Always follow applicable structural codes and the engineer-of-record specifications for joint design and bolt torque requirements. Ensure the bearing surface is clean and free of debris before seating the washer. Do not substitute plain-finish washers in corrosive or outdoor environments without verifying finish suitability with the project engineer.
