Holo-krome 86055 Button Socket Cap Screw M10x1.50 20mm

Product Description

The HOLO-KROME 86055 is a metric button socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features an M10x1.50 thread size with a 20mm length under head and is fully threaded. The button-style head provides a low-profile seating surface, while the hex socket drive accepts a 6mm hex key for installation. Manufactured from Grade 12.9 alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance in demanding service environments. It is suited for machine builders, millwrights, and maintenance technicians who require metric fasteners to ANSI/ASME and ASTM standards.

This screw is appropriate for use in close-clearance assemblies where a low-profile head is required and standard hex cap screws cannot be used due to space constraints. The fully threaded shank and right-hand thread direction make it compatible with standard M10 tapped holes. The black oxide finish provides a consistent appearance and light surface protection. Minimum order quantity is 100 pieces per order, with individual package quantity of 1.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load performance
• Button head profile reduces protrusion above the mating surface in tight assemblies
• 6mm hex socket drive for torque application with standard Allen or hex key tooling
• Black oxide finish for uniform appearance and mild corrosion resistance
• Fully threaded shank with right-hand M10x1.50 metric thread
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style metric fastener replacement for assemblies requiring M10x1.50 button socket cap screws per ANSI/ASME B18.3 and ASTM F835 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated 6mm hex key or socket driver. Verify that the mating tapped hole meets M10x1.50 thread specification and that the thread fit class is compatible before assembly. Clean threads and mating surfaces before installation to ensure proper seating. Always confirm torque requirements against the applicable engineering specification for the assembly; do not exceed the rated hardness of 38 HRC or over-torque into softer base materials.
