M20-2.5 × 150mm براغي رأس سداسي | فولاذ فئة 10.9 أصفر زنك | ملولبة جزئيًا (20 / عبوة)

The hex heads fit my socket perfectly, and the 10.9 grade feels robust enough for heavy clamping on my press. These M20 bolts came in handy for a machinery rebuild where I needed that partial thread to snug up a flange.

The partially threaded design made cinching down these M20 bolts on a steel frame much easier, and the yellow zinc coating looks like it will hold up well against the shop environment. Really solid feel from the Class 10.9 steel.

Installing these on a heavy press jig was a breeze with a socket; the 150mm length gave just the right reach through the bushing. The partial threading held tight without galling the bore.
