Holo-krome 72042 Hex Socket Cap Screw 6-32 Unc 1/2 in

Product Description

The HOLO-KROME 72042 is a hex socket cap screw designed for fastening applications that require a clean, low-profile head and reliable clamping strength. It features a 6-32 UNC thread and measures 1/2 inch in length under the head. Drive is a 7/64-inch hex socket. The fastener is machined from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. Fully threaded along its shank, this screw is suited for secure engagement in tapped holes. Qualified machinists, millwrights, HVAC technicians, and general trade professionals working with precision assemblies are the typical installers.

This screw is used across a wide range of light-duty and precision fastening applications, including electrical enclosures, HVAC equipment panels, machine guards, instrumentation housings, and general sheet-metal assemblies. The 6-32 UNC thread is one of the most common machine screw threads in American trade work, making this fastener a standard choice for equipment fabrication and field repair. The black oxide finish suits indoor or low-moisture environments where a non-reflective, dark appearance is preferred.

Key Features

• 6-32 UNC fully threaded alloy steel construction for consistent thread engagement
• Black oxide coating provides mild corrosion resistance and a non-reflective finish
• 7/64-inch hex drive accepts standard hex keys and socket drivers
• 1/2-inch length under head suits shallow-thread applications in panels and enclosures
• Meets ASME B18.3 and ASTM A574 standards for socket cap screws

Compatibility

Designed as a standard 6-32 UNC socket cap screw for use in any application calling for an ASME B18.3 or ASTM A574-compliant alloy steel hex socket fastener with a 1/2-inch length under head.

Installation Notes

Installation requires a 7/64-inch hex key or ball-end driver. Ensure the mating tapped hole conforms to 6-32 UNC thread specifications before driving the fastener. De-energize and lock out any electrical or mechanical equipment before accessing fastener locations in live panels or assemblies. Do not over-torque; alloy steel cap screws in small diameters can be damaged if driven beyond the thread or fastener rating.
