براغي ذات رأس سداسي M30-3.5 × 240 مم | فئة 8.8 من الصلب العادي | ملولبة جزئيًا (2/عبوة)

I needed some heavy-duty fasteners for a big machine base, and these M30 hex heads threaded in perfectly with my impact wrench. The 240mm length gave enough grip without being awkward, and the 8.8 steel feels solid. Exactly what I hoped for.

The hex head grabbed my 30mm socket perfectly, no slipping even when I torqued it down hard on the press frame. Class 8.8 steel feels solid, and the partial threading saved me from having to stack washers to get the right grip.

The partially threaded shaft made alignment in the flange hole much easier than a fully threaded bolt would have. I used these on a press frame repair and they torqued down solid without any stretching. Only wish the pack came with matching washers for the price.
