Value Collection 872369PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 872369PR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 1/2-13 UNC thread size with a 2-3/4 inch length under head and is partially threaded for reliable clamping force in through-hole and blind-hole configurations. The screw is machined from alloy steel and finished with a zinc plating for corrosion resistance in general shop and maintenance environments. The 3/8 inch hex drive socket interface is compatible with standard Allen keys and hex bit drivers. This fastener is specified to ASME B18.8 and ASTM A574 standards, making it suitable for demanding load-bearing applications.

This socket cap screw is used in a wide range of industrial and mechanical applications including machinery assembly, fixture building, tooling, and equipment maintenance. The partially threaded shank provides a bearing surface for precise alignment between mating components. It is appropriate for both production and MRO use where a high-strength, low-profile cap head fastener is required. The UNC thread form is the standard coarse-pitch inch thread used throughout North American manufacturing and repair environments.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard inch-threaded components
• 2-3/4 inch length under head with partial threading for shank bearing surface
• 3/8 inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Zinc-plated finish provides corrosion resistance in general-use environments
• Conforms to ASME B18.8 dimensional standards

Compatibility

Designed as an OEM-style replacement or standard-use hex socket cap screw for any application requiring a 1/2-13 UNC partially threaded alloy steel fastener conforming to ASME B18.8 and ASTM A574 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a calibrated torque wrench and the appropriate 3/8 inch hex key or socket bit. Ensure mating threads are clean and free of debris before installation. Consult applicable torque specifications from the equipment manufacturer or a standard fastener torque chart for 1/2-13 alloy steel fasteners. Do not substitute this fastener in applications requiring stainless steel or other corrosion-resistant alloys without verifying material compatibility.
