Value Collection 204283 Hex Head Cap Screw 5/8-11 2-1/2 in 316 Ss

Product Description

The VALUE COLLECTION 204283 is a hex head cap screw designed for fastening applications requiring corrosion-resistant hardware. Manufactured from Grade 316 stainless steel, this fastener features a 5/8-11 UNC thread size and a 2-1/2 inch length under head. The 15/16 inch hex drive allows standard wrench engagement. Grade 316 stainless steel provides superior resistance to chlorides and harsh environments compared to Grade 304, making it a preferred choice for marine, chemical processing, and outdoor structural assemblies. This screw is installed by millwrights, pipefitters, maintenance mechanics, and general tradespeople working in corrosive or wet service conditions.

This cap screw is suited for use in applications where moisture, salt spray, or chemical exposure is a concern. Typical installations include marine hardware, food processing equipment, pool and waterpark infrastructure, and industrial piping supports. The UNC thread form is compatible with standard inch-series tapped holes and nuts. Its hex head profile allows torque application with standard open-end, box-end, or socket wrenches and impact drivers commonly used in trade settings.

Key Features

• Grade 316 stainless steel construction for enhanced corrosion resistance in chloride-rich environments
• 5/8-11 UNC thread size for compatibility with standard inch-series hardware
• 2-1/2 inch length under head for medium-depth fastening applications
• 15/16 inch hex drive for engagement with standard wrenches and sockets
• Inch measurement system with UNC thread standard

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 5/8-11 UNC tapped holes, nuts, and threaded inserts in Grade 316 stainless steel service applications.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with fastener torque requirements for stainless steel hardware. Use appropriate anti-seize compound on stainless threads to prevent galling during installation. Ensure the mating tapped hole or nut is also rated for the intended service environment. Follow applicable mechanical and structural codes for the specific application.
