Value Collection 872421BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 872421BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from alloy steel with a zinc-plated finish, this fastener resists corrosion while delivering the tensile strength required in demanding environments. It features a 5/8-11 UNC thread, a 2.5-inch length under head, and a 1/2-inch hex drive for use with standard hex keys or Allen-style drive tools. The partially threaded shank provides clamping force appropriate for through-bolt and mating-thread applications. Compliance with ASME B18.8 and ASTM A574 confirms dimensional accuracy and mechanical performance standards.

This cap screw is suited for general mechanical assembly, maintenance and repair operations, and OEM fabrication work across manufacturing, HVAC equipment mounting, electrical enclosure construction, and industrial machinery. The 5/8-11 UNC thread pitch is a standard coarse-thread configuration widely used in steel-to-steel connections where assembly speed and resistance to cross-threading are priorities. Alloy steel construction makes this fastener appropriate where carbon steel would be insufficient for load or fatigue requirements.

Key Features

• 5/8-11 UNC coarse thread for broad compatibility with standard tapped holes
• 2.5-inch length under head with partial threading for positive clamping
• 1/2-inch hex socket drive accepts standard Allen keys and hex bit sockets
• Alloy steel construction meets ASTM A574 mechanical requirements
• Zinc-plated finish provides baseline corrosion resistance
• Conforms to ASME B18.8 dimensional standards

Compatibility

Designed as a standard 5/8-11 UNC hex socket cap screw for use in any application requiring an ASME B18.8 or ASTM A574 compliant fastener with a 1/2-inch hex drive and 2.5-inch length under head.

Installation Notes

Installation is performed with a 1/2-inch hex key, T-handle, or hex bit socket driver. Verify that the mating tapped hole meets 5/8-11 UNC thread specifications before installation. Apply appropriate thread lubricant or thread-locking compound per the assembly specification. Follow applicable industry torque standards for 5/8-inch alloy steel fasteners as specified in the equipment or structure design documents.
