براغي رأس مقبس M16-2 × 90 مم | محرك مقبس سداسي | ملولبة جزئيًا | فولاذ سبائك فئة 12.9 مطلي بالزنك (25 / عبوة)

The partially threaded design made these perfect for a custom fixture I was building, where I needed a precise clamp point. The zinc plating on the class 12.9 steel also looks clean and hasn't shown any rust after a few weeks in my shop.

Needed a heavy-duty bolt for a jig I was building, and the Class 12.9 rating gives me real confidence in the threads holding up under torque. The partial threading made alignment a breeze during assembly.

The hex socket drive gripped my Allen key perfectly with zero rounding, and the zinc plating looks clean enough to leave exposed on my fixture builds. Threads ran smooth into tapped holes, no binding even at this 90mm length. For 25 pieces at this grade, they’re a solid buy.
