Value Collection 31300 Uss Flat Washer Size 10 Steel

Product Description

The VALUE COLLECTION 31300 is a USS flat washer designed for use with size 10 screws in general fastening and assembly applications. Manufactured from steel with a zinc-plated finish, this washer provides corrosion resistance suited to a range of indoor and light-duty environments. It measures 3/16 inches inside diameter, 9/16 inches outside diameter, and 3/64 inches thick. The USS (United States Standard) series features a wider outside diameter relative to SAE washers, distributing clamp load over a broader surface area. Plumbers, electricians, HVAC technicians, and maintenance trades commonly use USS washers when securing fasteners to softer or thinner substrates where a wider bearing surface reduces pull-through risk.

This washer is suited for light mechanical assembly, equipment mounting, pipe support bracketing, and general maintenance tasks across residential and commercial trade work. The zinc plating provides a basic barrier against oxidation in dry or mildly humid conditions. It is sold individually but carries a minimum order quantity of 500 pieces, making it appropriate for stocking in a fastener bin or bulk supply situation where consistent washer size and finish are needed across multiple jobs.

Key Features

• USS series profile with wider OD for broader load distribution compared to SAE flat washers
• Steel construction provides reliable mechanical strength for general fastening tasks
• Zinc-plated finish offers basic corrosion resistance in dry and mildly humid environments
• 3/16 inches inside diameter fits size 10 screws without excessive play
• 3/64 inches thickness keeps the washer profile low while maintaining structural integrity
• Inch measurement system for compatibility with standard imperial fastener sets

Compatibility

Designed as a USS-standard flat washer for use with size 10 screws in imperial fastener applications across general mechanical, electrical, plumbing, and HVAC assembly tasks.

Installation Notes

Installation requires no special tools beyond standard hand or power drivers appropriate to the mating fastener. Always power down equipment and relieve system pressure before servicing any component that uses fasteners. Do not exceed the rated clamp load of the mating screw or bolt. Ensure the washer seats flat against the substrate before final torque is applied to the fastener.
