Value Collection 011439P Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 011439P is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. It features a 5/8-11 UNC thread and measures 6 inches in length under the head. The screw is partially threaded, which provides a smooth shank section that resists shear forces in load-bearing joints. Manufactured from alloy steel and finished with a black oxide coating, it delivers solid corrosion resistance and surface hardness suited to demanding shop and field conditions. Drive engagement is via a 1/2 inch internal hex socket. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards.

This cap screw is appropriate for use in heavy-duty mechanical and structural applications where socket-drive access is required and high clamp load is critical. Typical installation scenarios include machine frames, tooling fixtures, and industrial equipment maintenance. The partially threaded shank makes it well suited for applications requiring precise bolt alignment or shear resistance across a joint interface. Maintenance technicians, machinists, and millwrights commonly specify this type of fastener in both OEM builds and field repair work.

Key Features

• 5/8-11 UNC thread for high-load fastening
• 6 inches length under head, partially threaded for shear resistance
• 1/2 inch hex socket drive for internal wrench engagement
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application accepting a 5/8-11 UNC partially threaded socket head cap screw with a 6 inch length under head.

Installation Notes

Install with a calibrated torque wrench and the appropriate 1/2 inch hex key or socket drive bit. Verify mating thread condition and hole depth before installation. Always de-energize or lock out equipment before fastener replacement on live machinery per applicable OSHA lockout/tagout procedures. Do not substitute this fastener in applications requiring full-thread engagement without confirming adequate thread engagement length in the mating material.
