Value Collection R63036061 Hex Head Cap Screw 5/16-18

Product Description

The VALUE COLLECTION R63036061 is a hex head cap screw designed for secure mechanical fastening in corrosive or wet environments. Manufactured from Grade 316 stainless steel, this fastener delivers superior resistance to chlorides, saltwater, and chemical exposure compared to standard 304 stainless. It features a 5/16-18 UNC thread pattern and a 2-inch length under head, making it suitable for medium-duty structural and equipment assembly applications. The 1/2-inch hex drive is compatible with standard wrenches and sockets. Installers across plumbing, HVAC, pool service, and marine trades rely on Grade 316 hardware where long-term corrosion resistance is required.

This screw is used in residential and light commercial applications where fasteners are exposed to moisture, pool chemicals, treated lumber, or outdoor elements. Typical uses include mounting brackets, equipment frames, pipe supports, and enclosure panels in environments where carbon steel or 304 stainless would corrode prematurely. The UNC thread form is the standard coarse-thread designation for inch-series fasteners, ensuring broad compatibility with tapped holes and standard hex nuts in this size class.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance in chloride and chemical environments
• 5/16-18 UNC coarse thread for reliable engagement with standard inch-series tapped holes and nuts
• 2-inch length under head suits medium-depth fastening applications
• 1/2-inch hex drive compatible with standard wrenches and sockets
• Inch measurement system with UNC thread standard for domestic and North American equipment compatibility

Compatibility

Designed as a standard inch-series hex head cap screw for use with 5/16-18 UNC tapped holes, hex nuts, and threaded inserts in residential and commercial mechanical, plumbing, HVAC, and pool equipment installations.

Installation Notes

Installation is performed by qualified tradespeople using a standard 1/2-inch wrench or socket driver. De-energize or shut off any equipment before fastening components to live systems. Avoid mixing stainless steel fasteners with dissimilar metals in direct contact to minimize galvanic corrosion risk. Apply a compatible anti-seize compound when installing stainless fasteners into stainless tapped holes to prevent galling during installation and future removal.
