Holo-krome 86005 M3x0.50 Button Cap Screw 12mm Grade 12.9

Product Description

The HOLO-KROME 86005 is a metric button socket cap screw designed for high-strength fastening applications. It features an M3x0.50 thread size, a 12mm length under the head, and a low-profile button head driven by a 2mm hex socket. Manufactured from Grade 12.9 alloy steel with a black oxide finish, this fastener delivers exceptional tensile strength and moderate corrosion resistance in compact assemblies. Hardness is rated at 38 HRC. It conforms to ANSI/ASME B18.3 and ASTM F835 standards, making it a reliable choice for precision mechanical and industrial applications. Installation is typically performed by maintenance technicians, machine builders, or field service professionals.

This screw is suited for use in tight clearance environments where a standard hex head or pan head would not seat properly. The button head profile reduces interference in assemblies with closely spaced components. Typical applications include machine frames, equipment enclosures, jigs, fixtures, and general mechanical assemblies requiring a flush or low-profile fastener in a metric thread pattern. The fully threaded shank provides full thread engagement throughout the clamped material depth. A minimum order quantity of 100 pieces applies to this SKU.

Key Features

• Grade 12.9 alloy steel construction rated at 38 HRC hardness for high-strength applications
• Low-profile button head reduces clearance requirements in tight assemblies
• 2mm hex socket drive for precise torque application in confined spaces
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Fully threaded shank with M3x0.50 right-hand thread and 4G/6G fit class
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style metric button socket cap screw for use in assemblies specifying an M3x0.50 thread with a 12mm length under the head and button head profile per ANSI/ASME B18.3 and ASTM F835.

Installation Notes

Installation requires a 2mm hex key or socket driver. Ensure mating threads are clean and free of debris before driving the fastener. Do not exceed the rated torque specification for Grade 12.9 M3 hardware as published in applicable ANSI or engineering references. A minimum order quantity of 100 pieces applies to this part number.
