Value Collection 872357PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 872357PR is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. It features a 1/2-13 UNC thread size with a 1-1/4 inch length under head and is fully threaded along its entire length. The 3/8 inch hex drive accepts standard hex keys and Allen wrenches. Constructed from alloy steel with a zinc-plated finish, this fastener delivers solid corrosion resistance for general-purpose use. It conforms to ASME B18.8 and ASTM A574 standards, making it suitable for applications requiring a recognized fastener specification. Machinists, millwrights, and maintenance technicians are the typical end users.

This cap screw is suited for use in machinery assembly, equipment mounting, jig and fixture fabrication, and general mechanical maintenance. The fully threaded configuration maximizes thread engagement across the full clamping length, which is useful when fastening thinner materials or when full thread purchase is required throughout the joint. The zinc-plated alloy steel construction makes it appropriate for indoor and light-duty outdoor environments where moderate corrosion resistance is needed.

• Zinc-plated finish provides moderate corrosion resistance for general service environments
• Conforms to ASME B18.8 dimensional standard

Compatibility

Designed as a standard-dimension replacement or stock fastener for any application requiring a 1/2-13 UNC hex socket cap screw with a 1-1/4 inch length under head and a 3/8 inch drive, per ASME B18.8 and ASTM A574 specifications.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 3/8 inch hex key or Allen driver. Ensure mating threads are clean and free of debris before installation. Follow the equipment manufacturer's torque specifications for the joint design and application. Always use appropriate fastener-grade hardware when replacing existing cap screws to maintain joint integrity.
