Value Collection 015265PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 015265PR is a partially threaded hex socket cap screw designed for high-strength bolted assemblies in mechanical, industrial, and trade applications. Manufactured from alloy steel with a black oxide finish, this fastener offers good corrosion resistance and lubricity for installation and removal. The 3/8-16 UNC thread size and 2.25-inch length under head make it suited for medium-duty clamping joints. Drive engagement is through a 5/16-inch internal hex socket, requiring a standard hex key or Allen driver. This screw conforms to ASME/ANSI B18.3, ASTM A574, and IFI 124 standards.

This socket cap screw is used in a wide range of residential and commercial mechanical assemblies, including machine frames, brackets, jigs, fixtures, and equipment enclosures. The partial threading allows for precise clamping of thick material stacks where full threading would reduce clamping force. It is installed by machinists, millwrights, pipefitters, HVAC technicians, and general maintenance trades wherever a low-profile, high-strength fastener with internal hex drive is required.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes
• Partially threaded shank for strong clamping in thick-stack joints
• Alloy steel construction for high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and reduces galling
• 5/16-inch hex socket drive accepts standard hex keys and driver bits
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard-specification replacement or stock fastener for any application requiring a 3/8-16 UNC partially threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Install with a calibrated hex key or T-handle driver sized to the 5/16-inch socket. Ensure the mating tapped hole is clean and free of debris before threading. De-energize and lock out any equipment before replacing fasteners on live machinery per applicable OSHA lockout/tagout procedures. Apply thread lubricant or anti-seize if the fastener will be exposed to moisture or high heat to prevent galling on removal.
