Value Collection MP72286 Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION MP72286 is a partially threaded hex socket cap screw designed for high-strength bolted assemblies in industrial, mechanical, and structural applications. Manufactured from alloy steel with a black oxide finish, this fastener meets ASME B18.3 and ASTM A574 standards, making it suitable for demanding load-bearing connections. The 5/8-11 UNC thread and 4-inch length under head provide solid clamping depth in thicker workpieces. Drive engagement is through a 1/2-inch internal hex socket, requiring a standard hex key or Allen-drive socket tool. This pack contains 5 screws.

This screw is used in general mechanical assembly, equipment fabrication, machine guarding, and structural fastening tasks where a flush or low-profile cap head is required. The partial threading allows full thread engagement in tapped holes at the correct depth without thread interference along the shank. Typical installers include millwrights, machinists, maintenance technicians, and industrial contractors working with steel weldments, frames, or machinery bases.

Key Features

• 5/8-11 UNC thread form for standard unified coarse thread engagement
• 4-inch length under head for use in deeper tapped holes and thick-section assemblies
• Partially threaded shank reduces thread interference and improves shear load performance
• Alloy steel construction meets ASTM A574 high-strength socket cap screw requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 1/2-inch hex socket drive for use with standard hex keys or Allen-drive tools

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw suitable for tapped through-holes or blind holes with 5/8-11 UNC thread form in steel, iron, and compatible structural materials.

Installation Notes

Installation requires a 1/2-inch hex key or Allen-drive socket. Ensure the mating tapped hole is clean, properly formed to 5/8-11 UNC specification, and free of debris before threading in the fastener. Follow applicable torque guidelines from engineering documentation or standard fastener references for ASTM A574 alloy steel cap screws. Apply thread lubricant or anti-seize as required by the assembly specification to achieve consistent clamp load.
