Holo-krome 72014 Hex Socket Cap Screw 3-48 Unc 3/8 in

Product Description

The HOLO-KROME 72014 is a hex socket cap screw designed for precision fastening in tight-clearance applications where a standard hex head wrench cannot reach. The screw features a 3-48 UNC thread size, a 3/8-inch length under the head, and a 5/64-inch hex drive. It is fully threaded and manufactured from alloy steel with a black oxide finish for corrosion resistance. This fastener meets ASME B18.3 and ASTM A574 standards. It is well suited for use in mechanical assemblies, equipment maintenance, and light industrial applications where a low-profile, high-strength socket cap fastener is required.

The 72014 is appropriate for applications demanding a small-diameter, fine-thread cap screw. The 3-48 UNC thread size and compact form factor make it a common choice in instrumentation, precision machinery, and equipment panels. The black oxide coating provides mild corrosion resistance and reduces surface reflectivity. This screw is typically installed by machinists, mechanical assemblers, HVAC equipment technicians, and field service professionals working on control panels or mechanical housings.

Key Features

• 3-48 UNC thread size with full threading along the shank
• 3/8-inch length under the head for shallow fastening applications
• 5/64-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• Conforms to ASME B18.3 dimensional standard for socket cap screws

Compatibility

Designed as an OEM-style replacement or standard-stock hex socket cap screw for mechanical assemblies requiring a 3-48 UNC fully threaded fastener with a 5/64-inch hex drive.

Installation Notes

Installation requires a correctly sized 5/64-inch hex key or Allen driver to avoid rounding the socket. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Do not overtighten small-diameter screws, as alloy steel fasteners at this thread size are susceptible to thread damage under excessive torque. Installer should follow applicable equipment manufacturer torque guidance and standard mechanical assembly practices.
