Value Collection SSWASHER9790 Uss Flat Washer 3/8 in

Product Description

The VALUE COLLECTION SSWASHER9790 is a USS-pattern flat washer designed for use with 3/8-inch screws and fasteners. Manufactured from Grade 18-8 stainless steel, it provides reliable corrosion resistance in wet, outdoor, and chemically exposed environments. The washer measures 7/16 inches inside diameter, 1 inch outside diameter, and 0.083 inches thick. USS flat washers follow a wider outer-diameter standard than SAE washers, distributing clamping load over a larger surface area. This type of hardware is installed by electricians, plumbers, HVAC technicians, millwrights, and general contractors wherever a corrosion-resistant, load-spreading fastener solution is required.

This washer is suited for residential and light commercial construction, mechanical assemblies, plumbing installations, and general maintenance applications. The USS flat washer profile is commonly specified where bolt or nut bearing surfaces need protection from pull-through or surface damage, especially in stainless fastener assemblies exposed to moisture or outdoor conditions. Grade 18-8 stainless steel makes this washer appropriate for use in coastal environments, food-service settings, and any installation where carbon steel hardware would be prone to rust or staining.

Compatibility

Designed as a standard USS flat washer for use with 3/8-inch screws and bolts in inch-measurement fastener assemblies.

Installation Notes

Install with the appropriate 3/8-inch fastener following applicable mechanical or structural specifications for the application. Ensure mating hardware is also stainless steel or a compatible alloy to prevent galvanic corrosion at the joint. Power down or de-energize any equipment before servicing fastened assemblies in electrical or mechanical panels. Hand-thread fasteners before applying final torque to avoid cross-threading.
