Value Collection B10127 Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION B10127 is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at 5/8-11 UNC with a 3-3/4 inch length under head, this fastener is driven by a 1/2 inch hex key and is manufactured from alloy steel with a black oxide coating for corrosion resistance and a clean finished appearance. It meets ASME/ANSI B18.3 and ASTM A574 standards, confirming suitability for demanding load-bearing joints. Machinists, maintenance technicians, and mechanical contractors reach for this size when securing heavy equipment, fixtures, and structural components.

This screw is well-suited for general industrial maintenance, machine assembly, and fabrication work where a high-strength socket cap fastener is required. The partial threading allows for precise clamping force between joined materials without thread engagement through the full grip length. Sold in a pack of 10, this SKU works for both single-repair scenarios and light production use.

Key Features

• 5/8-11 UNC thread size for compatibility with standard coarse-thread tapped holes
• 3-3/4 inch length under head with partial threading for controlled clamping
• 1/2 inch hex drive for use with standard hex keys or Allen wrenches
• Alloy steel construction rated to ASTM A574 for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light glare
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a direct-fit replacement or new-install fastener for any standard 5/8-11 UNC tapped hole application requiring a socket cap screw per ASME/ANSI B18.3 specifications.

Installation Notes

Installation requires a 1/2 inch hex key or Allen-style driver rated for the fastener grade. Confirm the mating tapped hole is clean, properly sized for 5/8-11 UNC, and free of debris before driving. Apply thread lubricant or anti-seize as appropriate for the service environment. Follow applicable mechanical or structural codes for torque requirements specific to the joint design and alloy steel grade.
