Value Collection 011407PR Hex Socket Cap Screw 1/2-20 Unf

Product Description

The VALUE COLLECTION 011407PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural components. It features a 1/2-20 UNF thread size with a 3-inch length under head and is partially threaded to allow for controlled clamping in bolted joints. The 3/8-inch hex drive allows installation with a standard Allen wrench or hex bit. Made from alloy steel with a black oxide finish, this screw provides corrosion resistance and meets ASME/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for demanding service environments.

This screw is suited for use in manufacturing, maintenance, and repair operations where fine-thread fastening is required. The 1/2-20 UNF fine thread provides tighter thread engagement than coarse-thread equivalents, making it appropriate for applications requiring vibration resistance or precise torque control. Typical users include machinists, millwrights, industrial maintenance technicians, and mechanical contractors working on machine frames, equipment housings, and precision assemblies.

Key Features

• 1/2-20 UNF fine thread for strong, vibration-resistant clamping
• 3 inches length under head, partially threaded for controlled joint clamping
• 3/8-inch hex drive compatible with standard Allen wrenches and hex-bit drivers
• Alloy steel construction meets ASTM A574 requirements for mechanical properties
• Black oxide coating provides mild corrosion resistance and reduced light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or stock fastener for industrial and mechanical assemblies requiring a 1/2-20 UNF partially threaded hex socket cap screw with a 3-inch length under head.

Installation Notes

Installation is typically performed by machinists or mechanical maintenance technicians using a 3/8-inch hex key or Allen-drive bit. Ensure mating threads are clean and free of debris before installation. Power down and de-energize any equipment before servicing fasteners on live machinery. Do not exceed the torque rating specified by the equipment manufacturer for this thread size and material grade.
