Value Collection -30604-13 Hex Head Cap Screw 5/8-11

Product Description

The VALUE COLLECTION -30604-13 is a partially threaded hex head cap screw designed for industrial and commercial fastening applications. Manufactured from Grade 316 stainless steel with a bright, uncoated finish, it offers strong resistance to corrosion in wet, chemical, and marine environments. The screw measures 5/8-11 thread size with a 5-inch length under the head and follows the UNC (Unified National Coarse) thread standard. This fastener is suited for use by maintenance technicians, pipefitters, HVAC installers, and general trade professionals who require reliable, corrosion-resistant hardware in demanding service conditions.

This hex head cap screw is used in a wide range of commercial and industrial applications where stainless steel fasteners are specified for corrosion resistance. Typical uses include equipment mounting, structural assemblies, pipe flange connections, and mechanical systems exposed to moisture or chemicals. Grade 316 stainless steel is commonly specified in coastal environments, food service, pharmaceutical, and chemical processing installations. The partially threaded shank provides a bearing surface for clamping applications where a smooth shaft section is required between mating components.

Key Features

• Grade 316 stainless steel construction provides superior corrosion resistance compared to Grade 304
• Partially threaded shank allows for controlled clamping and a smooth bearing surface
• 5/8-11 UNC thread standard ensures compatibility with standard inch-series nuts and tapped holes
• 5-inch length under head accommodates thicker assemblies and multi-layer stackups
• Bright, uncoated finish suitable for applications where coatings may be restricted or unnecessary
• Hex head drive accepts standard 15/16-inch wrenches and sockets for reliable installation torque

Compatibility

Designed for use with standard 5/8-11 UNC-threaded nuts, washers, and tapped holes conforming to inch-series thread standards.

Installation Notes

Installation is performed by maintenance technicians, pipefitters, or general trade personnel using standard hand tools or power tools fitted with the appropriate socket. Always de-energize, depressurize, or lock out associated equipment before fastener removal or replacement in mechanical systems. Apply appropriate thread lubricant or anti-seize compound when joining stainless steel fasteners to prevent galling during tightening. Follow applicable mechanical or structural codes for proper fastener torque and joint design requirements.
