براغي رأس سداسية M20-2.5 × 50 مم | فولاذ فئة 10.9 عادي | ملولبة بالكامل (20/عبوة)

Wrapped a socket around one of these and torqued it down into some heavy equipment frame—the 10.9 steel held perfectly without any deformation. Threads cut clean and engaged smoothly from start to finish.

The Class 10.9 rating is no joke—these bolts took a serious torque load without stripping, and the fully threaded length made alignment a breeze on my press frame. Wrapped in a greasy rag after use, they still show zero wear.

These bolts fit perfectly on my milling machine jig; the fully threaded shaft gave me plenty of grip depth. The hex heads are sharp and didn't strip even under high torque from my impact wrench.
