Value Collection 015371PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 015371PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural components. It features a 1/2-13 UNC thread size with a 3-inch length under the head and is partially threaded for secure engagement in tapped holes. The 3/8-inch hex drive socket allows installation with a standard Allen key or hex bit driver. Constructed from alloy steel with a black oxide coating, this fastener delivers corrosion resistance and a low-reflectance finish suited for industrial and maintenance environments. Installation is performed by licensed mechanics, millwrights, pipefitters, or experienced maintenance technicians.

This screw is suited for general mechanical fastening, machine assembly, and equipment maintenance where a high-strength socket head cap screw meeting ASME/ANSI B18.3, ASTM A574, and IFI 124 standards is required. The 1/2-13 UNC coarse thread pattern provides reliable engagement in steel and cast-iron tapped holes. Typical applications include industrial machinery, hydraulic equipment mounting, fixtures, and structural steel assembly. The black oxide finish reduces surface rust in light-moisture environments without affecting dimensional tolerances.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes in steel and cast iron
• 3-inch length under head with partial threading for optimized clamping force
• 3/8-inch hex socket drive compatible with standard Allen keys and hex bit drivers
• Alloy steel construction rated to ASTM A574 for high tensile and proof load strength
• Black oxide coating provides mild corrosion resistance and low-reflectance surface finish
• Meets ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard-dimension replacement or service fastener for any application requiring a 1/2-13 UNC partially threaded hex socket cap screw per ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians using a 3/8-inch hex key or socket bit. Ensure all equipment is de-energized and depressurized before replacing fasteners in live assemblies. Thread engagement should be confirmed in the tapped hole before torquing to the appropriate specification for the joint and material. Follow applicable ASME or facility maintenance codes for fastener installation and inspection intervals.
