Value Collection MP72238 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION MP72238 is a 1/2-13 UNC hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from alloy steel and finished with a black oxide coating, this fastener delivers solid corrosion resistance and reduces light reflection in service environments. The screw measures 2-1/2 inches in length under the head and is partially threaded. It is driven with a 3/8-inch hex key. This product is sold in a pack of 5 and meets ASME B18.3 and ASTM A574 standards, making it a reliable choice for engineers, machinists, and maintenance technicians.

This hex socket cap screw is suited for use in machine building, equipment assembly, tooling fixtures, and structural fastening where a countersunk or flush-mount profile is required. The 1/2-13 UNC thread pitch is a coarse-thread standard widely used in general industrial and mechanical applications. The black oxide alloy steel construction handles moderate corrosion environments and is commonly found in manufacturing facilities, fabrication shops, and MRO operations.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility in standard industrial fastening
• 2-1/2 inch length under head with partial threading for clamping strength
• Alloy steel construction meets ASTM A574 for high-strength performance
• Black oxide finish provides moderate corrosion resistance and low-glare surface
• 3/8-inch hex drive for use with standard hex keys or Allen wrenches
• Conforms to ASME B18.3 dimensional standards

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw for use in any application requiring ASME B18.3 and ASTM A574 compliant fasteners.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a properly sized 3/8-inch hex key or socket driver. Ensure mating threads are clean and free of debris before driving. Do not overtighten — use a calibrated torque wrench and consult the equipment manufacturer's specifications for proper torque values. Thread lubricants or anti-seize compounds may be applied based on the service environment.
