براغي رأس سداسية M20-1.5 × 120 مم | فولاذ فئة 8.8 مطلي بالزنك | ملولبة جزئياً (10 / عبوة)

The hex head makes it easy to get a good grip with a socket, and the M20-1.5 threads threaded cleanly into the pre-tapped hole I have. The zinc coating gives a nice matte finish that matches other hardware on my assembly.

Used these to bolt down some heavy equipment, and the partial threading made alignment a lot easier. The hex head grabbed firmly with a socket, no stripping even at decent torque. Exactly what I needed for a solid M20 industrial fastener.

Zinc plating looks uniform across all ten, no bare spots or rough edges where the threads cut in. The partial threading on these M20s made alignment in the coupling a lot easier than dealing with fully threaded bolts, and the Class 8.8 steel feels solid under torque.
