براغي رأس سداسية M30-3.5 × 180 مم | فولاذ فئة 10.9 عادي | ملولبة جزئيًا (2/عبوة)

Installed these on a heavy-duty press bracket yesterday. The 10.9 grade steel gave me confidence the partial thread would handle the shear load without any issues.

Machined a new flange coupling this weekend and these M30s torqued down smoothly without stripping the hex, the partial thread gave just the right grip depth for the assembly. Two per pack is a bit stingy for the price, but the 10.9 steel took my impact wrench like a champ.

I needed some serious hardware for a large press project, and these M30 cap screws fit the bill perfectly. The 10.9 grade steel is reassuringly tough, and the hex head sits firmly in my wrench without any play.
