براغي رأس سداسية M16-2 × 65 مم | فئة 10.9 فولاذ عادي | خيط جزئي (25/عبوة)

I used these to secure a heavy steel bracket to a concrete floor, and the 10.9 grade steel handled the torque without any deformation. The hex head fit my socket wrench perfectly, and the partial threading made alignment much easier.

The partial threading on these M16 bolts really helped when securing a heavy steel frame—grabbed the nuts perfectly without binding. They're solid Class 10.9, so I have no worries about stripping under load. Exactly what I needed for industrial assembly work.

Installed these on a heavy press table; the hex heads gave my socket wrench a solid bite without any rounding. The 10.9 steel feels tough and durable, perfect for the job.
