Holo-krome 86033 Button Socket Cap Screw M6x1.00 20mm

Product Description

The HOLO-KROME 86033 is a metric button socket cap screw designed for applications requiring a low-profile fastener with high tensile strength. It features an M6x1.00 thread and a 20mm length under the head, with a 4mm hex socket drive for use with standard Allen keys or hex bit drivers. Manufactured from Grade 12.9 alloy steel with a black oxide finish, this fastener meets ANSI/ASME B18.3 and ASTM F835 standards. The 12.9 material grade delivers hardness of 38 HRC, making it appropriate for high-stress mechanical assemblies where a flush or near-flush head profile is required. It is fully threaded and carries a right-hand thread direction.

This button socket cap screw is suited for precision mechanical assemblies, machine frames, fixtures, and tooling applications where a domed low-profile head is preferred over a standard socket head cap screw. The black oxide finish provides moderate corrosion resistance and reduces light reflection in optical or instrumentation assemblies. The 4G thread fit class allows for standard tolerance engagement in metric-tapped holes. Typical installers include machinists, mechanical technicians, and industrial maintenance professionals working on equipment requiring compact fastener clearance.

Key Features

• Grade 12.9 alloy steel construction with 38 HRC hardness for high-load applications
• M6x1.00 fully threaded, 20mm length under head
• Low-profile button head at 10.5mm diameter and 3.3mm head height
• 4mm hex socket drive compatible with standard Allen keys and hex bit drivers
• Black oxide finish for moderate corrosion resistance and reduced surface reflectivity
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in metric-tapped M6x1.00 holes conforming to standard 4G or 6G thread fit classes in industrial machinery, fixtures, and mechanical assemblies.

Installation Notes

Installation requires a 4mm hex key or hex socket driver. Ensure the mating tapped hole meets M6x1.00 metric thread specifications before installation. Disconnect power or de-energize any equipment before fastening components on live machinery. Do not exceed the rated clamp load for the Grade 12.9 material grade when torquing.
