Value Collection 39750 Uss Flat Washer 1/4 in Steel

Product Description

The VALUE COLLECTION 39750 is a USS flat washer sized for 1/4-inch screws, manufactured from Grade 8 steel with a zinc yellow dichromate finish. USS flat washers feature a wider outer diameter than standard SAE washers, providing a larger bearing surface that distributes load and reduces fastener pull-through in softer materials. With a 5/16-inch inner diameter, 3/4-inch outer diameter, and 1/16-inch thickness, this washer is sized to the USS standard specification. The zinc yellow dichromate coating adds corrosion resistance for use in moderately demanding environments. Plumbers, electricians, HVAC technicians, and general contractors use these washers daily in mechanical assembly, pipe support, equipment mounting, and structural fastening applications.

This washer is suited for light-duty to medium-duty fastening applications in both residential and commercial settings. The USS-standard geometry makes it appropriate wherever increased load distribution is required compared to a narrower SAE washer. Typical installations include equipment brackets, conduit supports, pipe hangers, and general mechanical assemblies. Sold individually per piece with a minimum order quantity of 200 units, making them appropriate for stocking in service vans, shop bins, or project staging areas.

Key Features

• USS flat washer standard — wider OD than SAE for greater load-bearing surface
• Grade 8 steel construction for high tensile strength
• Zinc yellow dichromate finish provides corrosion resistance
• 5/16-inch inner diameter fits 1/4-inch screw shanks with standard clearance
• 3/4-inch outer diameter and 1/16-inch thickness conform to USS dimensional standards
• Minimum order quantity of 200 pieces supports bulk stocking for trade use

Compatibility

Designed for use with 1/4-inch fasteners in USS flat washer applications where inch-system measurement and a wider bearing surface are required.

Installation Notes

Install this washer between the fastener head or nut and the mating surface to distribute clamping load. Ensure the inner diameter is concentric with the fastener shank before torquing. Verify that the zinc dichromate finish is compatible with the service environment, particularly where dissimilar metals or chemical exposure may be present. No special tools are required for installation beyond standard hand or power fastening equipment.
