براغي رأس مقبس M12-1.75 X 110mm | محرك مقبس سداسي | ملولبة جزئياً | فئة 12.9 سبيكة فولاذية مؤكسدة حرارياً سوداء (50 / عبوة)

The hex socket drive seated perfectly on my Allen wrench with zero wobble, and the partial threading made alignment in my jig a breeze. These M12s held up through a full day of heavy clamping without a hint of stripping.

The black oxide finish on these is a nice touch—it’s even and doesn’t flake, and the hex socket drive sits perfectly flush for my tooling setups. Threads on all fifty were clean, no burrs, and they torqued down without binding.

Installed a set of these on a custom jig for a milling job – the 12.9 alloy steel feels rock solid under heavy torque. The partially threaded shaft made alignment on thicker steel plates much easier than fully threaded bolts would.
