Value Collection 015357PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 015357PR is a fully threaded hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. Built from alloy steel with a black oxide finish, this fastener offers good corrosion resistance and reduced light glare in field conditions. It features a 1/2-13 UNC thread size and a 1-1/4 inch length under head, driven by a 3/8 inch hex key. This screw meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for demanding load-bearing installations. Machinists, millwrights, and maintenance technicians are the typical installers.

This hex socket cap screw is suited for residential and commercial mechanical assemblies where a recessed drive fastener is required. Common applications include machine frames, tooling fixtures, equipment housings, and structural brackets where a flush or low-profile head is needed. The fully threaded shank provides consistent thread engagement across the full 1-1/4 inch clamping length, which is especially useful in thinner material stacks or when maximum grip is required throughout the joint.

Key Features

• 1/2-13 UNC thread size for broad compatibility with standard inch-series tapped holes
• Fully threaded shank provides maximum thread engagement at 1-1/4 inches under head
• Alloy steel construction delivers high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and low-reflectance appearance
• 3/8 inch hex drive accommodates standard hex keys and socket drivers
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard-duty replacement or new-installation hex socket cap screw for any 1/2-13 UNC tapped hole requiring a 1-1/4 inch under-head length and a 3/8 inch hex drive.

Installation Notes

Installation is performed by machinists, millwrights, or general maintenance technicians using a 3/8 inch hex key or Allen-style socket driver. Clean and inspect tapped holes before installation to ensure thread integrity. Apply thread-locking compound or anti-seize as appropriate for the service environment. Never use an impact driver on socket cap screws without a rated hex-socket adapter, as this risks rounding the drive recess.
