براغي رأس سداسي M18-1.5 X 80mm | فولاذ فئة 8.8 عادي | ملولبة جزئياً (20/عبوة)

Had a small vibration issue on a jig I was building, and swapping to these Class 8.8 hex heads made the whole assembly feel rock solid. The partial threading let me get a nice tight grip without stripping anything.

I was nervous about the partially threaded design, but these M18 bolts gripped perfectly in my hydraulic press frame. The hex head took a socket wrench without slipping, and at 80mm length the thread engagement was just right.

Used these M18x1.5 bolts to secure a heavy-duty industrial press table, and the 80mm length with partial threading let me grab just the right amount of thread in the frame. The hex head gave a solid grip with my socket wrench without any stripping. They’ve held up perfectly under constant vibration
