Value Collection MP72228 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION MP72228 is a hex socket cap screw designed for high-strength fastening applications in mechanical, industrial, and trade assemblies. It features a 1/2-13 UNC thread size and is fully threaded along a 1-1/4 inch length under head. The 3/8 inch hex drive socket head accepts a standard hex key or Allen wrench for secure torque application. Constructed from alloy steel with a black oxide finish, this fastener resists corrosion and provides a clean, uniform appearance. It meets ASME B18.3 and ASTM A574 standards, confirming dimensional accuracy and mechanical strength. Sold in a package of 10.

This screw is appropriate for general mechanical assembly, machine building, equipment maintenance, and structural fastening tasks where a recessed-drive, high-strength cap screw is required. The 1/2-13 UNC coarse thread pattern is well-suited for use in steel, cast iron, and other ferrous base materials across both light industrial and heavy-duty applications. Installers in HVAC, plumbing, electrical, and general mechanical trades will recognize this as a standard fastener for panel mounting, bracket attachment, and equipment assembly tasks.

Key Features

• 1/2-13 UNC fully threaded coarse thread for reliable engagement in ferrous materials

• Packaged in quantities of 10 per package

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw suitable for 1/2-13 UNC tapped holes in steel, cast iron, and compatible ferrous assemblies across general mechanical and industrial applications.

Installation Notes

Installation is performed using a 3/8 inch hex key or hex bit driver rated for the fastener size. Ensure the receiving tapped hole is clean and free of debris before threading. Always de-energize and lock out equipment before fastening or removing hardware on powered systems. Fastener torque should follow the applicable equipment manufacturer specifications or industry standard torque tables for 1/2-13 alloy steel cap screws.
