Value Collection 93704 Uss Flat Washer 1/2 in 18-8 Ss

Product Description

The VALUE COLLECTION 93704 is a USS flat washer designed for use with 1/2 inch screws and fasteners. Manufactured from 18-8 stainless steel, this washer provides corrosion resistance suitable for wet, outdoor, and chemically exposed environments. The USS pattern delivers a wider outer diameter than SAE equivalents, distributing clamp load across a larger bearing surface to reduce fastener pull-through and protect softer base materials. With a 9/16 inch inner diameter, a 1-3/8 inch outer diameter, and a thickness of 0.109 inches, this washer meets standard USS dimensional specifications. Sold individually with a minimum order quantity of 100 pieces, it is suited for high-volume mechanical, plumbing, and structural assembly work.

This washer is appropriate for residential and commercial applications where stainless steel hardware is specified to resist rust and staining. Common installation scenarios include plumbing fixture mounting, HVAC equipment attachment, electrical panel support structures, pool and spa equipment assemblies, and general mechanical fastening in corrosive or moisture-prone environments. Plumbers, HVAC technicians, electricians, and general contractors regularly use USS flat washers of this type when code or application conditions require non-corroding hardware.

Compatibility

Designed as an OEM-style and general-use replacement or stock washer for 1/2 inch screw and bolt assemblies requiring USS flat washer dimensions in 18-8 stainless steel.

Installation Notes

USS flat washers are installed by mechanical trades, plumbers, electricians, and HVAC technicians as part of standard fastener assemblies. Place the washer onto the fastener shank before driving into the base material to distribute clamp load. Ensure the mating fastener and nut are also stainless steel or a compatible alloy to prevent galvanic corrosion in wet environments. No special tools are required for installation beyond standard hand or power wrenches appropriate for the fastener size.
