Value Collection MP72280 Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION MP72280 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. The fastener features a 5/8-11 UNC thread size with a 3-inch length under the head and is partially threaded along its shank. The internal hex drive accepts a 1/2-inch hex key, allowing high torque application in confined spaces. Manufactured from alloy steel with a black oxide finish, this screw meets ASME B18.3 and ASTM A574 standards, making it appropriate for demanding load-bearing installations. This listing includes a package of 5 screws.

This screw is suited for machinery assembly, fabrication, tooling fixtures, and general industrial fastening where a flush or low-profile head is required. The partially threaded shank provides a bearing surface that helps align mating components and reduces the risk of thread engagement in the unthreaded portion of the grip length. Machinists, millwrights, maintenance technicians, and fabricators commonly use this fastener type in both production and field repair settings.

Key Features

• 5/8-11 UNC thread size for high-load fastening applications
• 3-inch length under head with partial threading for accurate grip-length control
• 1/2-inch internal hex drive for high-torque installation with a standard hex key or Allen driver
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME B18.3 dimensional standards

Compatibility

Designed as a standard 5/8-11 UNC hex socket cap screw for use in any application requiring an ASME B18.3 or ASTM A574 compliant fastener of this thread size and length.

Installation Notes

Installation should be performed by a qualified mechanic, machinist, or millwright familiar with fastener torque requirements for alloy steel cap screws. Always verify that the mating thread material and thread class are compatible with 5/8-11 UNC before installation. Use the correct 1/2-inch hex key or socket driver to avoid rounding the drive recess. Ensure the receiving hole is clean and free of debris before threading to prevent galling or cross-threading.
