براغي رأس سداسية M30-3.5 × 100 مم | فولاذ مقاوم للصدأ 316 | ملولبة بالكامل (5 / عبوة)

Got these for a fabrication project and the 316 stainless is definitely a step up from standard steel—no rust worries here. The fully threaded design made alignment a breeze during assembly.

Installed these on a marine railing and the 316 stainless held up perfectly through a week of salt spray with no rust. The hex head made it easy to drive them in with a socket.

The threads on these M30 bolts are surprisingly clean and started by hand without any binding. They feel substantial and the 316 stainless finish looks like it will hold up well outdoors. Exactly what I needed for a heavy-duty equipment mount.
