Value Collection 837395PR Hex Socket Cap Screw 1/2-20 Unf

Product Description

The VALUE COLLECTION 837395PR is a hex socket cap screw designed for high-strength fastening applications across industrial and mechanical assemblies. It features a 1/2-20 UNF thread size with full threading along its 1-1/4 inch length under head. The fastener is machined from alloy steel and finished with a zinc-plated coating that provides corrosion resistance in standard service environments. Drive engagement is achieved with a 3/8 inch hex socket. This screw meets ASTM B695 specifications and is suited for maintenance professionals, machinists, and assembly technicians working on precision mechanical equipment.

This fastener is used in applications requiring fine-thread engagement, including machine frames, fixtures, and mechanical assemblies where vibration resistance and controlled torque retention are priorities. The 1/2-20 UNF thread pitch provides finer thread engagement compared to coarse-thread equivalents, making it appropriate for harder materials and applications requiring tighter clamp loads. Minimum order quantity is 10 pieces.

Key Features

• 1/2-20 UNF fine thread for precise engagement and vibration resistance
• Fully threaded 1-1/4 inch length under head maximizes thread engagement
• Alloy steel construction provides high tensile strength
• Zinc-plated finish offers corrosion protection in standard environments
• 3/8 inch hex socket drive for use with standard hex keys and socket tooling
• Meets ASTM B695 fastener standard

Compatibility

Designed as a standard 1/2-20 UNF hex socket cap screw suitable for use in machinery, fixtures, and mechanical assemblies requiring fine-thread alloy steel fasteners with hex socket drive.

Installation Notes

Installation is performed with a 3/8 inch hex key or socket drive tool. Ensure mating threads are clean and free of debris before installation. De-energize and lock out any equipment before servicing fastened assemblies per applicable safety procedures. Do not substitute with coarse-thread fasteners in applications specified for UNF thread engagement.
