Holo-krome 64012 Button Socket Cap Screw 6-32 Alloy Steel

Product Description

The HOLO-KROME 64012 is a 6-32 button socket cap screw designed for threaded fastening applications requiring a low-profile head and high-strength alloy steel construction. The button head style provides a rounded, flush-sitting profile that resists snagging and spreading load across the mating surface. Driven by a 5/64-inch hex socket, this screw is fully threaded to 0.5 inches under the head and meets ANSI/ASME B18.3 and ASTM F835 standards. The black oxide finish offers mild corrosion resistance and reduces surface reflectivity. Hardness is rated at 38 HRC, making it suitable for demanding mechanical assemblies. Licensed tradespeople and maintenance technicians working on equipment panels, brackets, and enclosures will encounter this fastener type regularly.

This screw is suited for use in light to medium-duty mechanical assemblies where a low-profile fastener head is required. The 6-32 UNC thread form with a 3A fit class ensures consistent engagement in standard tapped holes. Typical applications include equipment enclosures, sheet metal assemblies, electronic chassis, and precision mechanical components where head clearance is limited. The fully threaded shank allows thread engagement along the full length in shallow tapped holes.

Key Features

• Button head style with 0.262-inch head diameter provides low-profile, snag-resistant fastening
• 5/64-inch hex socket drive for precise torque application in confined spaces
• Alloy steel construction with 38 HRC hardness for high-strength performance
• Black oxide finish for mild corrosion resistance and reduced reflectivity
• 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 6-32 UNC button socket cap screw for use in any application requiring an ANSI/ASME B18.3 compliant fastener with a 3A thread fit class in a right-hand threaded hole.

Installation Notes

Installation requires a 5/64-inch hex key or hex socket bit driver. Ensure the mating tapped hole meets 6-32 UNC thread specifications before driving the screw. Power down and de-energize any equipment before servicing fastened assemblies on electrical enclosures or panels. Do not exceed the rated hardness load limits by substituting this fastener in applications requiring higher-grade hardware specifications than ASTM F835.
