Holo-krome 86063 Button Socket Cap Screw M12x1.75 20mm

Product Description

The HOLO-KROME 86063 is a metric button socket cap screw designed for high-strength fastening applications requiring a low-profile head. It features an M12x1.75 thread size, 20mm length under head, and is fully threaded with a right-hand thread direction. The 8mm hex socket drive allows for installation with a standard hex key or socket driver. Built from Grade 12.9 alloy steel with a black oxide finish, this fastener delivers high tensile strength combined with moderate corrosion resistance. Licensed trade professionals and industrial maintenance technicians specify Grade 12.9 fasteners where standard hardware-grade bolts are insufficient.

The 86063 is suited for mechanical assemblies, machine frames, tooling fixtures, and equipment where a flush or low-profile fastener head is required. The button head design distributes clamping load over a wider bearing surface than a standard socket head cap screw, making it appropriate for use in sheet metal, plastic housings, and thin-flange applications. The black oxide finish provides a clean appearance and light surface protection in dry or mildly humid environments.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load ratings
• Button head profile minimizes protrusion and distributes clamping load over a larger area
• 8mm hex socket drive compatible with standard hex keys and socket drivers
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Fully threaded along the 20mm shank length for maximum thread engagement in shallow bosses
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style and general-use replacement or spec fastener for metric M12x1.75 button socket cap screw applications conforming to ANSI/ASME B18.3 and ASTM F835 standards.

Installation Notes

Installation should be performed by a qualified mechanic or industrial maintenance technician using a calibrated torque wrench and the appropriate 8mm hex key or bit socket. Always verify mating thread class compatibility before assembly, as this fastener carries a 4G and 6G thread fit class designation. De-energize and lock out any equipment before fastener replacement on machinery. Do not exceed the rated torque for Grade 12.9 M12 fasteners as published by the applicable engineering standard.
