Holo-krome 86059 Button Cap Screw M10x1.50 30mm Grade 12.9

Product Description

The HOLO-KROME 86059 is a metric button socket cap screw designed for high-strength fastening applications. It features an M10x1.50 thread size with a 30mm length under the head, driven by a 6mm hex socket. Manufactured from grade 12.9 alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance in a low-profile button head form. The fully threaded shank and right-hand thread direction make it a straightforward fit for standard metric assemblies. Machinists, millwrights, and maintenance technicians install this fastener where a flush or near-flush head profile is needed without sacrificing clamp load.

This screw is suited for light to medium structural assemblies, machine guarding, brackets, and equipment enclosures where head clearance is limited. The button head profile distributes load across a wider bearing surface compared to a standard socket head cap screw. It conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards, making it appropriate for precision mechanical applications in industrial, commercial, and maintenance environments. Sold in multiples of 10 per order.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Button head profile offers low-profile seating with a wide bearing surface
• 6mm hex socket drive for precise torque application with standard hex keys or bits
• Fully threaded shank with 4G and 6G thread fit class conformance
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard metric replacement or new-installation button socket cap screw for any assembly requiring an M10x1.50 fully threaded fastener conforming to ANSI/ASME B18.3 and ASTM F835 specifications.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a calibrated torque wrench and the appropriate 6mm hex key or socket bit. Confirm mating thread class compatibility before installation. Inspect threads for damage before seating, and avoid over-torquing, which can strip threads or fracture the fastener at extreme clamp loads. Apply thread-locking compound only if required by the assembly specification.
