براغي رأس مقبس سداسية M10-1.5 × 90 مم | رأس مسطح بمحرك سداسي | ملولبة جزئيًا | فولاذ سبائكي من الفئة 12.9 مطلي بالزنك (50 / عبوة)

The 12.9 alloy steel is the real deal here—these screws handled the torque on my press fixture without a hint of flex. Thread engagement on the partially threaded section is spot-on for blind holes, and the zinc plating has already survived a week of shop grime.

Installed these on a custom jig I'm building for a milling machine — the partial threading gave me plenty of grip without bottoming out in the blind hole. Finish looks clean and uniform across all 50 pieces.

The hex socket drive on these M10-1.5 x 90mm screws really helps with getting good torque in tight spots on my jig build. The 12.9 alloy steel feels much tougher than the standard hardware store bolts I've used before.
