براغي رأس سداسية M16-2 × 200 مم | فولاذ فئة 10.9 عادي | ملولبة جزئياً (6 / عبوة)

The hex profile grabbed my socket wrench cleanly on the very first try, and the 10.9 steel feels properly dense for heavy machinery work. Partially threaded design gave me just the right grip length for a thick flange setup without any slop.

These are substantial bolts, the 10.9 grade steel is definitely up to the job for our press repair. The partial threading is exactly what we needed to get a solid bite in the frame. They torqued down smoothly without any galling.

Threads are clean and the hex head fits a standard socket well, though being only partially threaded makes them a bit awkward for certain deep nut applications. They feel solid enough for medium-duty use, but I wish the package included more than just six for the price.
