براغي رأس مقبس M30-3.5 × 110 مم | محرك مقبس سداسي | ملولبة جزئيًا | سبائك فولاذ فئة 12.9 مؤكسد أسود حراريًا (5 / عبوة)

I needed a heavy-duty fastener for a jig I’m building, and the 12.9 alloy steel feels extremely solid for the torque I’m applying. The hex socket drive engaged perfectly with my wrench, no slipping at all.

The partial threading on these M30 cap screws gave me the exact grip length I needed for a heavy jig setup, and the 12.9 alloy steel feels rock solid under torque. They seated cleanly into the hex socket without any wobble.

The black oxide finish on these is flawless, and the hex socket drive seated perfectly with my torque wrench on the first try. The 110mm length gave me just enough thread engagement for a heavy jig I’m building, and the 12.9 alloy steel feels rock solid.
