Value Collection 011431BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 011431BR is a 5/8-11 UNC hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. The screw measures 4 inches in length under the head and is partially threaded, providing reliable clamping force in bolted joint configurations. It is driven with a 1/2-inch hex key. Manufactured from alloy steel and finished with a black oxide coating, it offers improved corrosion resistance compared to bare steel while maintaining tight dimensional tolerances required for precision assemblies. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding load-bearing applications.

This screw is appropriate for use in manufacturing, maintenance, and repair operations where high-strength socket cap fasteners are required. Partial threading makes it well-suited for through-bolt applications where grip length matters and bearing loads are concentrated in the shank area. It is commonly installed by machinists, millwrights, and industrial maintenance technicians in equipment assemblies, fixtures, and structural connections.

Key Features

• 5/8-11 UNC thread form for compatibility with standard inch-series tapped holes
• 4-inch length under head with partial threading for controlled grip length
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 1/2-inch hex drive for use with standard hex keys or socket drivers
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any tapped or clearance-hole assembly requiring a 5/8-11 UNC partially threaded socket cap fastener.

Installation Notes

Installation requires a 1/2-inch hex key or Allen-head socket driver. Clean and inspect the mating tapped hole before installation to ensure thread integrity. Apply thread-locking compound or fastener lubricant as required by the application specification. Power down and de-energize any equipment before accessing fastener locations in live machinery.
