Value Collection MP72174 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION MP72174 is a hex socket cap screw designed for high-strength fastening applications across mechanical assembly, maintenance, and industrial service work. Threaded to 3/8-16 UNC with a 3-inch length under the head, this fastener is partially threaded and driven with a 5/16-inch hex key. Constructed from alloy steel and finished with a black oxide coating, it resists corrosion and reduces light reflection in service environments. Machinists, millwrights, and maintenance technicians use this screw where a recessed drive and strong clamp load are required. Sold in a pack of 10.

This cap screw is suited for general industrial and mechanical applications requiring a standard UNC thread form. The 3/8-16 thread size and partial threading make it appropriate for through-hole and tapped-hole assemblies where a defined grip length is needed. The black oxide finish provides moderate corrosion protection in dry to mildly humid environments. Typical applications include machine frames, fixtures, equipment panels, and structural brackets in shop and field settings.

Key Features

• 3/8-16 UNC thread size with 3-inch length under head for deep fastening reach
• Partially threaded shank provides a defined grip zone for precision clamping
• 5/16-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASME B18.3 and ASTM A574 standards
• Black oxide coating reduces surface corrosion and glare in service environments
• Pack of 10 screws per package for stocking or job-lot use

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw suitable for tapped holes or through-hole assemblies conforming to ASME B18.3 dimensional requirements.

Installation Notes

Installation requires a 5/16-inch hex key or Allen-type bit driver rated for the fastener size. Ensure the mating tapped hole is clean and free of debris before installation. Follow applicable torque specifications for 3/8-16 alloy steel fasteners per your project or equipment service documentation. Avoid over-driving, which can strip threads or damage the socket recess.
