Value Collection 015271PR Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 015271PR is a partially threaded hex socket cap screw designed for high-strength fastening in mechanical, structural, and industrial applications. It features a 3/8-16 UNC thread size with a 3-inch length under head and a 5/16-inch hex drive socket. The fastener is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and a low-reflective appearance. Licensed tradespeople and maintenance technicians use this screw type where high tensile strength and a clean, flush-head profile are required. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards.

This socket cap screw is suited for machinery assembly, equipment mounting, jigs and fixtures, and general industrial fabrication where a recessed hex drive is preferred over an external hex head. The partial threading allows the smooth shank to act as a precision locating feature in close-tolerance bores. It is commonly used in metal-to-metal joints requiring controlled clamp load and resistance to vibration loosening.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes
• 3-inch length under head provides adequate grip in deeper joint stacks
• Partial threading allows smooth shank to serve as a locating pin in precision bores
• Alloy steel construction delivers high tensile and shear strength
• Black oxide finish reduces surface reflectivity and provides light corrosion resistance
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard replacement or new-installation hex socket cap screw for any application requiring a 3/8-16 UNC partially threaded fastener with a 5/16-inch internal hex drive.

Installation Notes

Installation requires a 5/16-inch hex key or Allen driver; use a torque wrench to meet joint design specifications. Ensure the mating tapped hole is clean and free of debris before threading. Power down or de-energize any machinery before accessing fastener locations in live equipment. Follow applicable industry standards and your organization's torque specifications for alloy steel socket cap screws of this grade.
