براغي رأس سداسية M12-1.75 × 40 مم | فئة 10.9 فولاذ أصفر زنك | ملولبة جزئيًا (100 / عبوة)

Used these to rebuild a piece of farm equipment and the 10.9 grade held up perfectly under heavy torque. The partial threading made alignment much easier in a tight spot.

The head sits perfectly in a 19mm socket and the partial threading made alignment much easier when assembling a heavy steel bracket. These bolts feel solid and the zinc coating has a nice uniform finish.

Used these to mount a jig onto the workbench and the partially threaded design made alignment a breeze. The hex heads grabbed cleanly with a socket, no stripping even under torque. Solid 10.9 strength for the price.
