Value Collection MP72242 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION MP72242 is a hex socket cap screw designed for secure, high-strength fastening in mechanical, structural, and industrial applications. It features a 1/2-13 UNC thread size with a 3-inch length under head and partial threading along the shank. The drive type is a 3/8-inch hex socket, requiring a standard hex key or Allen driver for installation. Constructed from alloy steel with a black oxide finish, this fastener offers solid mechanical strength and moderate corrosion resistance. It meets ASME B18.3 and ASTM A574 standards. Each package contains 5 screws.

This screw is suited for general industrial maintenance, machine assembly, and fabrication work where a flush or recessed drive head is required. The partial threading provides a grip zone on the shank, making it appropriate for clamping applications where a bearing surface is needed between the threaded and unthreaded portions. It is commonly installed by millwrights, maintenance technicians, and machinists working on equipment frames, tooling fixtures, and mechanical assemblies.

Key Features

• 1/2-13 UNC thread size with 3-inch length under head
• Partially threaded shank for clamping and precise fastening
• 3/8-inch hex socket drive for use with standard Allen keys or hex drivers
• Alloy steel construction meets ASTM A574 high-strength fastener specification
• Black oxide finish provides surface protection and reduces light reflection
• Conforms to ASME B18.3 dimensional standard for socket cap screws

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for applications requiring a 1/2-13 UNC hex socket cap screw with a 3-inch length under head. Verify thread pitch, length, and drive size against the existing fastener before installation.

Installation Notes

Installation requires a 3/8-inch hex key or Allen-drive socket. Torque to the specification called out in the equipment service documentation — do not substitute torque values from general fastener charts without confirming the joint design. Inspect threads for damage before installation. Black oxide finish is not a heavy corrosion barrier; apply thread-locking compound or anti-seize as appropriate for the environment.
