Value Collection FWUIS043-100BX Uss Flat Washer 7/16 in

Product Description

The VALUE COLLECTION FWUIS043-100BX is a USS flat washer designed for use with 7/16-inch screws and fasteners. Manufactured from steel with a plain finish, this washer distributes load across a bearing surface to prevent fastener pull-through and protect the workpiece. With a 1/2-inch inside diameter, 1-1/4-inch outside diameter, and 5/64-inch thickness, it conforms to USS (United States Standard) dimensional specifications. This pack contains 100 washers, making it suitable for ongoing maintenance, repair, and fabrication work where consistent hardware supply is needed.

These USS flat washers are used across a wide range of commercial, industrial, and trade applications including HVAC equipment mounting, plumbing fixture installation, electrical panel and conduit support, and general mechanical assembly. The USS series features a wider outer diameter relative to the screw size compared to SAE washers, providing greater load distribution. Suitable for use in structural and non-structural connections where a plain steel finish is acceptable.

Key Features

• USS flat washer profile provides wider load distribution than SAE equivalent
• Steel construction for strength in general mechanical and trade applications
• Plain finish suitable for interior applications or where coating is not required
• 1/2-inch inside diameter fits 7/16-inch screw or bolt shank with standard clearance
• 1-1/4-inch outside diameter distributes clamping force over a broad surface area
• Sold in a 100-piece pack to support volume repair and installation work

Compatibility

Designed for use with 7/16-inch screws and bolts in standard inch-measurement fastener applications across HVAC, plumbing, electrical, and general fabrication assemblies.

Installation Notes

Install with the washer seated flat against the workpiece surface before tightening the fastener. Ensure the inside diameter clears the fastener shank without binding. Plain-finish steel washers should not be used in direct contact with dissimilar metals in wet environments without appropriate corrosion protection measures. No special tools are required for installation.
