Value Collection 93707 Uss Flat Washer 7/8 in 18-8 Stainless

Product Description

The VALUE COLLECTION 93707 is a USS-pattern flat washer sized for 7/8-inch screws, manufactured from 18-8 stainless steel for corrosion resistance in demanding service environments. It measures 15/16 inches inside diameter, 2-1/4 inches outside diameter, and 0.165 inches thick, conforming to USS flat washer dimensional standards. The larger outer diameter of USS-style washers spreads clamping load over a wider bearing surface compared to SAE-pattern washers. Plumbers, electricians, HVAC techs, and general trades use flat washers like this to protect fastened surfaces, prevent pull-through on oversized holes, and distribute bolt load on softer substrates.

This washer is suited for both indoor and outdoor applications where moisture, humidity, or chemical exposure would cause carbon steel fasteners to corrode. Typical installation scenarios include mechanical equipment mounting, pipe hangers, structural connections, and electrical panel or conduit support work. The 18-8 stainless steel grade is widely accepted across residential and light commercial construction and maintenance applications.

Key Features

• USS flat washer pattern provides a wider outer diameter for increased load distribution
• 18-8 stainless steel construction resists rust, oxidation, and mild chemical exposure
• 15/16-inch inside diameter fits 7/8-inch nominal screw or bolt shank
• 2-1/4-inch outside diameter spreads clamping force over a broad bearing surface
• 0.165-inch thickness delivers consistent, rigid support under torque
• Inch-system dimensioning for straightforward integration with standard US fastener hardware

Compatibility

Designed for use with 7/8-inch nominal screws and bolts in USS flat washer applications across mechanical, plumbing, electrical, and HVAC installations.

Installation Notes

Install using standard hand tools; seat the washer flat against the bearing surface before torquing the fastener. Verify that the inside diameter clears the bolt shank without binding. In stainless-to-stainless assemblies, apply an anti-galling lubricant to the fastener threads to prevent seizure during tightening. Always follow applicable building codes and project specifications when selecting fastener hardware for structural or pressure-containing connections.
