Value Collection SSWASHER5476 Uss Flat Washer 3/8 in

Product Description

The VALUE COLLECTION SSWASHER5476 is a USS flat washer designed for use with 3/8-inch screws and fasteners. Manufactured from Grade 316 stainless steel, it provides strong corrosion resistance in wet, marine, and chemical-exposure environments. The washer measures 7/16 inches inside diameter, 1 inch outside diameter, and 0.083 inches thick. USS-pattern washers follow a wider outer-diameter standard compared to SAE washers, distributing clamp load over a broader surface area. Plumbers, pipefitters, marine contractors, and industrial maintenance technicians commonly specify Grade 316 hardware where chloride exposure or harsh conditions would degrade lower-grade fasteners.

This washer is suited for residential and commercial plumbing installations, marine and coastal construction, food-processing equipment assembly, and any bolted joint requiring stainless hardware. The USS flat washer pattern is commonly used under bolt heads and nuts to spread load, prevent surface damage, and reduce the risk of fastener pull-through in softer substrates. Grade 316 stainless steel is the preferred choice when Grade 304 stainless is insufficient for the corrosive environment.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chloride resistance
• USS flat washer pattern provides wider outer diameter for improved load distribution
• Fits 3/8-inch screws and bolts with 7/16-inch inside diameter clearance
• 0.083-inch thickness provides consistent clamping surface
• Inch measurement system for compatibility with standard US fastener hardware

Compatibility

Designed as an OEM-style replacement or standard-service USS flat washer for use with 3/8-inch fasteners in stainless steel hardware applications.

Installation Notes

Installation is performed by hand or with standard wrenching tools as part of a bolted assembly. Always ensure the inside diameter clears the fastener shank freely before torquing the joint. When assembling stainless steel fasteners, apply an anti-seize compound to reduce the risk of galling between mating stainless components. Follow applicable mechanical codes and project specifications for fastener torque requirements.
