Value Collection 015385PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 015385PR is a hex socket cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. This partially threaded fastener measures 6 inches under the head with a 1/2-13 UNC thread size, and accepts a 3/8-inch hex drive. Constructed from alloy steel with a black oxide finish, it provides corrosion resistance and a low-reflectivity surface suitable for demanding environments. Installation requires a 3/8-inch hex key or Allen drive tool. This screw meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards, making it appropriate for precision and load-bearing applications where dimensional and mechanical compliance is required.

This hex socket cap screw is suited for use in industrial machinery, tooling fixtures, equipment frames, and mechanical assemblies where a flush or recessed fastener head is required. The partially threaded shank provides strong clamping force between mated components. It is commonly installed by machinists, millwrights, and maintenance technicians working with steel or heavy-duty fabricated assemblies. The black oxide coating makes it a practical choice in environments where bare steel is acceptable but minor surface protection is desired.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard inch-series tapped holes
• 6-inch length under head provides deep reach for thick or stacked workpiece applications
• Partially threaded shank for improved clamping and shear resistance
• 3/8-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction delivers high tensile and yield strength
• Black oxide finish provides mild corrosion resistance and reduced surface glare
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards

Compatibility

Designed for use in standard 1/2-13 UNC tapped holes in steel, iron, and compatible base materials where a hex socket cap screw meeting ASME/ANSI B18.3 and ASTM A574 specifications is required.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 3/8-inch hex key or hex drive bit. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or anti-seize compound as required by the assembly specification. Do not exceed the rated torque for 1/2-13 UNC alloy steel fasteners as defined by the governing design standard.
