Value Collection 204226B Hex Head Cap Screw 3/8-16 Grade 316

Product Description

The VALUE COLLECTION 204226B is a hex head cap screw designed for fastening applications that demand corrosion resistance and mechanical strength. It features a 3/8-16 UNC thread with a 2-1/4 inch length under head and is partially threaded for proper clamping in through-hole and blind-hole assemblies. Manufactured from Grade 316 stainless steel with a bright, uncoated finish, this fastener resists corrosion in wet, chemical, and marine environments. It suits maintenance professionals, pipefitters, plumbers, and mechanical contractors working with stainless hardware in demanding service conditions.

This screw is suited for residential and commercial applications where standard carbon steel fasteners would corrode, including plumbing system supports, HVAC equipment mounting, pool and spa equipment enclosures, and general mechanical assemblies exposed to moisture or mild chemicals. The 3/8-16 UNC thread is a common coarse-thread standard found across a wide range of American fastener applications, making this screw broadly compatible with standard 3/8-16 threaded holes and nuts.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• 3/8-16 UNC coarse thread for compatibility with standard American inch-series threaded hardware
• Partially threaded shank provides proper clamping load in bolted joint assemblies
• Bright, uncoated finish — no plating to chip, flake, or react with stainless mating hardware
• 2-1/4 inch length under head suits medium-depth fastening applications

Compatibility

Designed as a standard inch-series hex head cap screw for use with 3/8-16 UNC threaded nuts, inserts, and tapped holes in stainless steel or compatible fastener assemblies.

Installation Notes

Installation is typically performed by mechanical contractors, pipefitters, or maintenance technicians using a standard hex wrench or socket set. Always degrease mating threads and consider applying an anti-seize compound when joining stainless steel to stainless steel to prevent galling. Torque to values appropriate for 3/8-16 Grade 316 stainless steel fasteners per applicable project specifications. Power down or depressurize any system before replacing fasteners on live equipment.
