Value Collection 31418 Uss Flat Washer 3/4 in Steel Zinc

Product Description

The VALUE COLLECTION 31418 is a USS flat washer designed for use with 3/4 inch screws and bolts in general mechanical, plumbing, and structural fastening applications. Constructed from steel with a zinc-plated finish, this washer distributes load across the fastening surface and helps reduce the risk of loosening under vibration. It measures 13/16 inches inner diameter, 2 inches outer diameter, and 0.1563 inches thick. The zinc plating provides a basic level of corrosion resistance suitable for indoor and light-duty outdoor installations. Plumbers, pipefitters, HVAC technicians, and general maintenance trades will find this washer compatible with standard 3/4 inch hardware.

This USS flat washer is suited for residential and light commercial applications where a wider bearing surface is needed compared to SAE-pattern washers. USS-pattern washers are commonly used in pipe flange connections, equipment mounting, and structural bolt assemblies. The larger outer diameter relative to screw size makes them a go-to choice when working with softer base materials or oversized clearance holes that require additional load distribution across a broader surface area.

Key Features

• USS pattern provides a wider outer diameter than SAE equivalents for greater load distribution
• Steel construction offers solid mechanical strength for fastening applications
• Zinc-plated finish provides basic corrosion resistance for general indoor and light outdoor use
• 13/16 inch inner diameter sized for standard 3/4 inch screw and bolt shafts
• 0.1563 inch thickness meets standard USS washer dimensional requirements

Compatibility

Designed as a standard USS-pattern flat washer for use with 3/4 inch screws and bolts in general mechanical, HVAC, plumbing, and structural fastening applications.

Installation Notes

Install with hand tools appropriate for the fastener being used. Ensure the washer seats flat against the mating surface before torquing the fastener. For corrosive environments, verify that zinc plating provides adequate protection or select a higher-grade finish. Power down or de-energize any equipment before servicing fastened assemblies on electrical or mechanical systems.
