Value Collection 015257PR Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 015257PR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade settings. Sized at 3/8-16 UNC with a 1-1/4-inch length under head, this screw is fully threaded and driven with a 5/16-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and high tensile strength for demanding assemblies. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it suitable for precision mechanical and structural fastening work performed by machinists, millwrights, and maintenance technicians.

This screw is commonly used in machine tool assemblies, jigs and fixtures, industrial equipment mounting, and structural mechanical connections where a recessed drive and high clamping force are required. The 3/8-16 UNC thread pitch suits a wide range of standard tapped holes in steel, aluminum, and cast iron components. The black oxide coating reduces light reflection and provides mild surface protection in dry or lightly oiled environments.

Key Features

• 3/8-16 UNC thread — standard coarse pitch for broad compatibility with tapped holes
• 1-1/4-inch length under head with full threading along entire shank
• 5/16-inch hex drive socket for torque-efficient installation with standard hex keys or Allen drivers
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Conforms to ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 3/8-16 UNC fully threaded hex socket cap screw with a 1-1/4-inch length under head and 5/16-inch drive.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 5/16-inch hex key or socket driver. Ensure mating tapped holes are clean and free of debris before threading. Apply thread lubricant or anti-seize as appropriate for the base material and operating environment. Always de-energize and lock out equipment before servicing assemblies that include this fastener.
