Value Collection 011393PR Hex Socket Cap Screw 1/2-20 Unf

Product Description

The VALUE COLLECTION 011393PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and structural components. It features a 1/2-20 UNF thread with a 1-inch length under head and is fully threaded along its entire shank. The 3/8-inch hex drive accepts a standard hex key or socket drive tool. Constructed from alloy steel with a black oxide coating, this screw provides corrosion resistance and reduced light reflection in industrial environments. It meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards.

This screw is suited for precision mechanical work where fine-thread engagement is required, including machine frames, hydraulic components, and close-tolerance assemblies. The fine 1/2-20 UNF thread pitch provides higher thread engagement per inch compared to coarse-thread equivalents, making it a common choice in vibration-prone applications. It is typically installed by machinists, millwrights, and maintenance technicians working on industrial or mechanical systems.

Key Features

• 1/2-20 UNF fine thread for increased engagement strength in tight-tolerance assemblies
• Fully threaded shank along entire 1-inch length under head
• 3/8-inch hex socket drive for use with standard hex keys or socket tools
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides mild corrosion resistance and reduced surface glare
• Conforms to ASME/ANSI B18.3 socket cap screw standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw compatible with any tapped 1/2-20 UNF hole requiring a 3/8-inch hex drive fastener in industrial or mechanical applications.

Installation Notes

Installation requires a 3/8-inch hex key or Allen-type socket driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread-locking compound or torque per the assembly specification when vibration is a concern. Verify hole thread class and engagement depth before final torque-down.
