Value Collection 31422 Uss Flat Washer 1-1/4 in Steel

Product Description

The VALUE COLLECTION 31422 is a USS flat washer designed for use with 1-1/4 inch screws and bolts. Made from Grade 2 steel with a zinc-plated finish, it distributes load across the fastener head or nut to protect the mating surface and reduce the risk of pull-through. The washer measures 1.368 inches inside diameter, 3.03 inches outside diameter, and 0.192 inches thick, conforming to USS (United States Standard) dimensional specifications. Tradespeople and assembly technicians use this washer in structural, mechanical, and general fastening applications where a wider bearing surface is required.

This washer is suited for residential and commercial construction, mechanical assemblies, HVAC equipment mounting, plumbing fixture installation, and general maintenance work. Its USS profile provides a larger outside diameter relative to the screw size compared to SAE washers, making it a common choice when working with softer base materials or oversized clearance holes. The zinc plating provides moderate corrosion resistance for indoor and light-duty outdoor use.

Key Features

• USS flat washer profile for wider load distribution compared to SAE series
• Grade 2 steel construction for reliable strength in general-purpose fastening
• Zinc-plated finish for moderate corrosion resistance
• Inside diameter: 1.368 inches — fits 1-1/4 inch screw or bolt shank
• Outside diameter: 3.03 inches for broad bearing surface coverage
• Thickness: 0.192 inches for consistent dimensional performance

Compatibility

Designed as a USS-standard flat washer for use with 1-1/4 inch screws and bolts in inch-measurement fastening systems across general construction, mechanical, and maintenance applications.

Installation Notes

Install by placing the washer over the bolt shank against the surface before threading the nut or driving into a tapped hole. Ensure the fastener and washer grade are matched appropriately for the load requirements of the application. For outdoor or high-moisture environments, consider a higher-grade corrosion-resistant finish, as zinc plating is rated for light-duty exposure only. Follow applicable building or mechanical codes for fastener assembly torque and hardware selection.
