براغي رأس سداسي M30-3.5 × 240 مم | فولاذ فئة 8.8 مطلي بالزنك | خيط جزئي (1 / عبوة)

Had to really torque these down for a machine base, and the hex head held up perfectly without stripping. The zinc plating looks solid and should resist rust in our shop environment.

Used these to bolt down a heavy jig frame in our shop, and the hex head grabbed a socket wrench cleanly without slipping. The zinc plating held up fine through a couple of oily shifts, no rust spots yet. Threads are cut deep and precise, so the partial threading made alignment fast.

The partially threaded design made alignment a breeze when I torqued it down with a socket. Zinc plating looks clean and didn’t chip during installation, which is more than I can say for other bolts I’ve used. Solid piece of hardware for the price.
