Value Collection 202978 Hex Cap Screw 3/8-16 316 Ss

Product Description

The VALUE COLLECTION 202978 is a fully threaded hex head cap screw designed for fastening applications that demand corrosion resistance and dimensional precision. Sized at 3/8-16 x 1-1/2 inches (length under head), this fastener is machined to Unified National Coarse (UNC) thread standards and manufactured from Grade 316 stainless steel with a bright, uncoated finish. Grade 316 stainless offers superior resistance to chlorides and harsh chemicals compared to Grade 304, making it a common choice for marine, food service, chemical processing, and outdoor environments. Licensed tradespeople and maintenance professionals turn to this screw when standard carbon steel fasteners would corrode prematurely.

This fastener suits residential and commercial installations where stainless hardware is specified by code or environmental condition. Typical applications include pipe flange bolting, equipment mounting, structural bracketing, and panel assembly in corrosive or washdown environments. It is sold individually, with a minimum order quantity of 10 pieces, making it suitable for both small repairs and bulk fastening tasks on larger service jobs.

Key Features

• Grade 316 stainless steel construction for strong chloride and chemical corrosion resistance
• Fully threaded along the 1-1/2 inch under-head length for maximum thread engagement
• 3/8-16 UNC thread form ensures compatibility with standard inch-series nuts and tapped holes
• Bright, uncoated finish — no plating to flake or degrade in wet or chemical environments
• Inch measurement system; length measured under head per ASME fastener conventions

Compatibility

Designed for use with standard 3/8-16 UNC inch-series hex nuts, flat washers, and tapped holes conforming to Unified National Coarse thread specifications.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 3/8-16 cap screw. Confirm mating threads are clean and free of debris before driving. In stainless-to-stainless applications, apply an anti-seize compound to reduce the risk of thread galling. Always torque to the value specified by the equipment manufacturer or applicable structural code.
