Holo-krome 76290 Hex Socket Cap Screw M10x1.5 15mm Alloy Steel

Product Description

The HOLO-KROME 76290 is a metric hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and construction assemblies. Sized at M10 x 1.50 with a 15mm length under head, this fastener is fully threaded and manufactured from alloy steel to a material grade of 12.9, placing it among the highest-strength standard fastener grades available. The black oxide finish provides moderate corrosion resistance and reduces light reflection in finished assemblies. It is driven with a hex key and meets ANSI B1.13M, ISO 4762, and ISO 898-1 standards. Installation is typically performed by machinists, millwrights, and mechanical contractors.

This screw is suited for medium-duty to high-strength metric fastening tasks where a recessed drive profile is required to keep fastener heads flush or below the mating surface. Fully threaded along its shank, the 76290 is well-suited for through-hole applications and shorter clamping lengths where thread engagement along the full grip length is an advantage. Its M10 x 1.50 thread pitch is the standard coarse metric thread for 10mm diameter fasteners, making it widely applicable in equipment manufacturing, machine frames, fixtures, and mechanical assemblies requiring high clamp load.

Key Features

• Grade 12.9 alloy steel construction for high-strength, high-torque fastening applications
• Fully threaded shank for maximum thread engagement in through-hole configurations
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Hex socket drive (hex key) for recessed installation in confined spaces
• Meets ANSI B1.13M, ISO 4762, and ISO 898-1 fastener standards
• M10 x 1.50 coarse metric thread pitch for broad equipment compatibility

Compatibility

Designed as an OEM-style metric hex socket cap screw for use in any M10 x 1.50 threaded application requiring a Grade 12.9 alloy steel fastener with a hex socket drive and black oxide finish.

Installation Notes

Installation requires an appropriately sized metric hex key or socket driver rated for Grade 12.9 fastener torque loads. Always verify thread engagement depth and mating material strength before applying full clamp load, as Grade 12.9 fasteners can generate significant clamping force. Clean and inspect threaded bores prior to installation to prevent cross-threading. Follow applicable mechanical assembly standards and equipment manufacturer torque specifications for M10 Grade 12.9 fasteners.
