Value Collection MP72248 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The Value Collection MP72248 is a hex socket cap screw designed for fastening applications that require a high-strength, recessed-drive connection. Manufactured from alloy steel with a black oxide coating, this screw carries a 1/2-13 UNC thread and measures 4 inches in length under the head. It is partially threaded, which provides clamping strength at the joint interface. The 3/8-inch hex drive accepts a standard hex key or bit driver. This screw meets ASME B18.3 and ASTM A574 standards, making it a recognized choice for mechanical assemblies in industrial, maintenance, and fabrication environments. The black oxide finish provides a degree of corrosion resistance and reduces light reflection on the fastener surface.

The MP72248 is suited for use in structural clamping, machine assembly, jig and fixture work, and general industrial fastening where socket-drive access is required. The 1/2-13 UNC coarse thread is widely used in steel and ferrous metal applications. Alloy steel construction supports the high tensile requirements common in heavy equipment, tooling, and conveyor or frame assemblies. Machinists, millwrights, maintenance technicians, and fabricators regularly use this fastener type across both commercial and industrial settings. This item is packaged in a quantity of 5.

Key Features

• Black oxide coating provides mild corrosion resistance and a low-reflectance finish
• Conforms to ASME B18.3 dimensional standards for socket cap screws

Compatibility

Designed as an OEM-style replacement or stock fastener for industrial and mechanical assemblies requiring 1/2-13 UNC hex socket cap screws conforming to ASME B18.3 and ASTM A574 standards.

Installation Notes

Installation is performed using a 3/8-inch hex key or socket-drive bit. Verify that the mating tapped hole is clean and free of debris before threading the screw. Always de-energize or lock out equipment before replacing fasteners on machinery or powered assemblies. Follow applicable industry standards for fastener installation procedures and torque requirements based on the specific application and joint design.
