Holo-krome 64032 Button Socket Cap Screw 10-24 5/8 in

Product Description

The HOLO-KROME 64032 is a 10-24 button socket cap screw designed for applications requiring a low-profile, high-strength fastener with a clean finished appearance. The hex socket drive accepts a 1/8-inch hex key for installation in tight clearances where a standard fastener head would interfere. Manufactured from alloy steel with a black oxide finish, the screw carries a hardness rating of 38 HRC and conforms to ANSI/ASME B18.3 and ASTM F835 standards. The fully threaded shank uses a UNC right-hand thread at 3A fit class, providing consistent engagement across standard tapped holes.

This screw is suited for mechanical assemblies, machine frames, enclosures, and fixtures where a flush or recessed button head is needed to avoid snagging or contact with adjacent components. The black oxide finish provides mild corrosion resistance in dry or lightly oiled environments. Licensed trades and industrial maintenance technicians commonly install these fasteners in equipment panels, brackets, and structural sub-assemblies. The 10-24 thread size is widely used in light-duty machine and electrical enclosure applications.

Key Features

• Button head profile reduces protrusion and interference in tight assemblies
• 1/8-inch hex socket drive for use with standard hex keys or hex bit drivers
• Alloy steel construction rated at 38 HRC hardness for reliable clamping strength
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Fully threaded shank with 3A fit class for consistent thread engagement
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 10-24 UNC replacement or new-installation fastener for tapped holes conforming to UNRC thread form in mechanical assemblies, panels, and fixtures.

Installation Notes

Installation requires a 1/8-inch hex key or matching socket bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate torque for the 10-24 alloy steel fastener class per relevant ASME standards - do not over-torque, as button head cap screws have lower drive torque limits than standard hex socket head cap screws. Power down any electrical equipment before installing fasteners in or near energized enclosures.
