Holo-krome 86006 Button Socket Cap Screw M3x0.50 16mm

Product Description

The HOLO-KROME 86006 is a metric button socket cap screw with an M3x0.50 thread and 16mm length under the head. It features a low-profile domed button head driven by a 2mm hex socket. Manufactured from grade 12.9 alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance. The fully threaded shank and right-hand thread direction follow metric standards, making it a reliable choice for precision assembly applications where clearance is limited and a flush, smooth head profile is required. Licensed tradespeople and assembly technicians install these in mechanical, structural, and equipment fabrication work.

This screw suits applications where a standard socket head cap screw would protrude too far or snag adjacent components. The button head profile is common in machine guards, panel assemblies, consumer equipment enclosures, and light structural connections. With a 4G and 6G thread fit class, it meets tight dimensional tolerances required in precision assemblies. The black oxide finish provides a uniform matte appearance and mild surface protection against oxidation in dry or lightly oiled environments.

Key Features

• Grade 12.9 alloy steel for high tensile and proof load strength
• Black oxide finish for mild corrosion resistance and low-glare appearance
• 2mm hex socket drive for use in confined spaces
• Fully threaded shank maximizes thread engagement across the full 16mm length
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards
• Right-hand thread direction, metric M3x0.50 pitch

Compatibility

Designed as an OEM-style metric button socket cap screw compatible with M3x0.50 threaded assemblies conforming to ANSI/ASME B18.3 and ASTM F835 standards.

Installation Notes

Install and remove using a calibrated 2mm hex key or hex socket bit. De-energize and lock out any equipment before fastener service per applicable safety procedures. Do not exceed the rated torque range for grade 12.9 M3 fasteners as specified by the governing fastener standard. Inspect threads for contamination or damage before installation to ensure proper fit class engagement.
