براغي رأس سداسية M30-3.5 × 280 مم | فولاذ درجة 8.8 غير مطلي | ملولبة جزئيًا (1 / عبوة)

The partially threaded section made alignment a breeze when I was bolting down a heavy base plate, and the hex head gave my socket a solid grip without slipping off. Finish is plain as advertised, but for the price these are exactly what a machine shop needs on hand.

The threads on these M30 bolts engaged perfectly with the nut on my assembly jig, no wobble at all. The 280mm length gave me just enough clearance for a thick steel plate. Solid Class 8.8 steel that really holds torque.

Installed these on a heavy press that kept loosening standard bolts. The M30 thread bites deep and the 8.8 steel feels solid enough for the job. Tightened with a socket and they haven't budged yet.
