Value Collection 015383PR Hex Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION 015383PR is a 1/2-13 UNC hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural connections. Manufactured from alloy steel and finished with a black oxide coating, this fastener delivers reliable clamping force with corrosion resistance in moderate environments. The screw measures 5.5 inches under the head and is driven with a 3/8-inch hex (Allen) key. It is partially threaded, which allows for precise shoulder engagement in clearance-hole applications. Machinists, millwrights, and maintenance technicians are the typical installers of this fastener type.

This cap screw is suited for both light industrial and heavy-duty mechanical assemblies where a recessed drive is required to maintain a low-profile head. The partially threaded shank makes it appropriate for applications requiring a smooth bearing surface between joined components, such as jig and fixture construction, machine frames, and equipment mounting. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, confirming its dimensional and mechanical compliance for professional and industrial use.

Key Features

• 1/2-13 UNC thread size for reliable engagement in standard tapped holes
• 5.5-inch length under head provides extended grip range for thick stack-ups
• Partially threaded shank allows smooth shank contact in clearance holes
• Alloy steel construction for high tensile and yield strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 3/8-inch hex drive for use with standard Allen keys and hex bit drivers
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any application calling for a 1/2-13 UNC partially threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is performed with a 3/8-inch hex key or hex bit driver. Ensure the mating tapped hole is clean and free of debris before threading to avoid galling the alloy steel threads. Power down and de-energize any equipment before fastener service on live machinery. Follow applicable ASME or facility torque specifications for 1/2-13 UNC fasteners based on the joint material and lubrication condition.
