مسامير رأس سداسية M18-1.5 X 110mm | فولاذ عادي فئة 10.9 | ملولبة جزئياً (25 / عبوة)

Torqued these to spec on a gearbox housing today and the partial threading gave just the right grip depth without bottoming out. The 10.9 hardness held up fine under the impact wrench.

These bolts drove in cleanly on my press rebuild—the hex head took a socket perfectly. A full box of 25 for this price is a solid deal for heavy-duty hardware.

Finally found a bolt that doesn't strip under heavy torque—these hex heads held up perfectly through a full day of equipment assembly. The 110mm length with partial threading gave me just the right grip for a spacer setup, and the class 10.9 steel feels seriously solid.
