Value Collection BDNA-31303 Uss Flat Washer 3/8 Inch

Product Description

The VALUE COLLECTION BDNA-31303 is a USS flat washer designed for use with 3/8 inch screws and bolts. Manufactured from steel with a zinc-plated finish, this washer distributes load across a fastened joint and helps prevent surface damage under bolt heads and nuts. The USS (United States Standard) pattern features a wider outer diameter relative to screw size compared to SAE washers, making it well suited for applications where greater load distribution is needed. The 7/16 inch inside diameter, 1 inch outside diameter, and 5/64 inch thickness conform to standard USS dimensional specifications. Plumbers, electricians, HVAC technicians, and general contractors use these washers in everyday mechanical and structural assembly work.

This washer is appropriate for residential and light commercial construction, mechanical systems, equipment mounting, and general fastening applications. The zinc plating provides a baseline level of corrosion resistance suitable for interior use and dry or mildly humid environments. It is commonly used wherever a 3/8 inch fastener requires a broad bearing surface, including structural connections, pipe hangers, equipment brackets, and panel assemblies.

Key Features

• USS pattern provides wider load-bearing surface compared to SAE flat washers of the same screw size
• Steel construction for strength in standard mechanical and structural applications
• Zinc-plated finish offers corrosion resistance in interior and low-moisture environments
• 7/16 inch inside diameter fits cleanly over 3/8 inch fastener shanks
• 1 inch outside diameter distributes clamping load across a broad contact area
• 5/64 inch thickness meets standard USS dimensional requirements

Compatibility

Designed for use with 3/8 inch screws and bolts in standard USS flat washer applications across mechanical, structural, and trade installation assemblies.

Installation Notes

Installation requires no special tools beyond standard hand or power tools appropriate to the fastener type. Place the washer over the fastener shank before seating the nut or bolt head against the work surface. Verify that the zinc-plated finish is adequate for the environment — do not use in continuously wet, submerged, or highly corrosive conditions without confirming finish suitability. Follow applicable codes and project specifications when using fasteners in structural or load-bearing assemblies.
