براغي ذات رأس سداسي M42-4.5 × 180 مم | فولاد من الفئة 10.9 عادي | خيط جزئي (1/عبوة)

The partially threaded section grabbed perfectly for our jig setup, and the 10.9 steel took a serious torque without stripping. These M42s fit the socket cleanly with zero wobble, feels like they'll outlast the machine they're holding.

Used these on a heavy equipment mount and the 180mm length gave me just enough grip through thick brackets. The hex heads seated cleanly with a socket wrench, no stripped edges. Class 10.9 held up fine under torque.

The 10.9 grade steel on these M42 bolts feels seriously robust, and the partial threading made alignment much easier when I was tightening them down with a socket wrench. Definitely a solid choice for heavy industrial work.
