Value Collection C85878 Uss Flat Washer 1/4 in Steel

Product Description

The VALUE COLLECTION C85878 is a USS flat washer designed for use with 1/4 inch screws and fasteners. It is manufactured from steel with a zinc-plated finish that provides basic corrosion resistance in general-purpose applications. The washer features a 5/16 inch inner diameter, a 3/4 inch outer diameter, and a 1/16 inch thickness, conforming to USS (United States Standard) dimensional specifications. This washer distributes fastener load across a broader bearing surface, reducing the risk of pull-through or surface damage on softer materials. Plumbers, electricians, HVAC technicians, and general maintenance trades commonly use USS flat washers throughout mechanical and structural assemblies.

This washer is suited for residential and light commercial maintenance, repair, and assembly work where a standard 1/4 inch USS flat washer is required. It fits applications involving bolts, machine screws, and carriage bolts of the corresponding screw size. The zinc plating makes it acceptable for indoor and mildly corrosive environments. It is sold individually but carries a minimum order quantity of 100 pieces, making it appropriate for stocking or bulk fastener replenishment in shop or field inventory.

Key Features

• USS flat washer profile provides a larger outer diameter relative to screw size for improved load distribution
• Steel construction with zinc-plated finish for basic corrosion resistance
• 5/16 inch inner diameter accommodates 1/4 inch screw shanks with standard clearance
• 3/4 inch outer diameter spreads clamp load across the bearing surface
• 1/16 inch thickness suits standard hardware applications
• Material Grade 8 steel for dependable mechanical performance

Compatibility

Designed as a standard USS flat washer for use with 1/4 inch screws, bolts, and fasteners in general mechanical and structural assemblies.

Installation Notes

Install with the appropriate 1/4 inch fastener using standard hand or power tools. Ensure the washer seats flat and fully against the bearing surface before torquing the fastener. For electrical or HVAC panel work, verify that fastener hardware meets applicable NEC or equipment manufacturer requirements. Zinc-plated steel washers are not recommended for continuously wet or highly corrosive environments where stainless steel or hot-dip galvanized hardware would be more appropriate.
