Holo-krome 86061 Button Socket Cap Screw M10x1.50 40mm

Product Description

The HOLO-KROME 86061 is a metric button socket cap screw with an M10x1.50 thread and a 40mm length under head. It is manufactured from Grade 12.9 alloy steel with a black oxide finish, making it suited for high-strength fastening applications where corrosion resistance and a low-profile head are required. The hex socket drive accepts a 6mm hex key. At 38 HRC hardness, this fastener delivers the clamping force needed in demanding mechanical assemblies. Licensed tradespeople and maintenance professionals working on equipment with metric fastener standards will find this screw compliant with ANSI/ASME B18.3 and ASTM F835.

This button socket cap screw is used in mechanical, industrial, and equipment assembly applications where a low-profile button head is preferred over a standard cap head. The fully threaded design and 4G/6G thread fit class make it suitable for metric-threaded assemblies requiring close tolerances. Typical applications include machine frames, fixtures, guards, and mounting brackets where Grade 12.9 high-strength fasteners are specified.

Key Features

• Grade 12.9 alloy steel construction with 38 HRC hardness for high-strength fastening
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Low-profile button head at 5.5mm head height and 17.5mm head diameter
• 6mm hex socket drive for standard metric hex key installation
• Fully threaded with right-hand thread direction
• Compliant with ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a metric button socket cap screw for use in M10x1.50 threaded assemblies conforming to ANSI/ASME B18.3 and ASTM F835 standards.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople familiar with metric fastener systems. Verify the mating thread is M10x1.50 and free of debris before installation. Use a calibrated torque wrench with the appropriate 6mm hex bit and follow the torque specifications defined by the equipment manufacturer or applicable engineering standards. Do not exceed rated torque values for Grade 12.9 fasteners in the mating material.
