Value Collection 015377PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 015377PR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. This fastener features a 1/2-13 UNC thread size with a 4-inch length under the head and is partially threaded, allowing for precise clamping force in bolted joints. The 3/8-inch hex drive accepts a standard Allen or hex key for installation and removal. Manufactured from alloy steel with a black oxide coating, the 015377PR offers improved corrosion resistance and reduced surface reflectivity compared to bare steel. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards.

This socket cap screw is suited for use in machine building, fixture fabrication, tooling, and general industrial assembly where a recessed-drive fastener is required. The partial threading engages a nut or tapped hole while leaving a smooth shank section that centers and aligns mating components. It is commonly installed by machinists, millwrights, maintenance technicians, and mechanical contractors working with threaded steel assemblies.

Key Features

• 1/2-13 UNC thread size for broad compatibility with standard inch-series tapped holes and nuts
• 4-inch length under head with partial threading for shank-guided clamping joints
• 3/8-inch hex socket drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 for high-strength fastener requirements
• Black oxide finish provides mild corrosion protection and low-glare appearance
• Conforms to ASME/ANSI B18.3 and IFI 124 dimensional and performance standards

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any 1/2-13 UNC tapped hole or with a matching 1/2-13 hex nut in industrial and mechanical assemblies.

Installation Notes

Installation is performed using a 3/8-inch hex key or Allen-drive bit. Ensure the tapped hole or mating nut is clean and free of debris before threading. Always torque fasteners to the value specified by the assembly engineer or applicable design standard, and never exceed the rated capacity of the tapped material. Follow applicable mechanical and structural codes for the specific application.
