براغي رأس سداسية M36-4 × 160 مم | فولاذ فئة 10.9 عادي | خيط جزئي (2 / عبوة)

These bolts feel incredibly solid, and the partial threading made aligning them in the equipment housing a lot less fiddly than I expected. They seated flush with a standard socket, and the class 10.9 rating gives me real confidence they'll hold up under load.

The threads are clean and precise, so they threaded into the tapped hole with zero wobble. With a 36mm socket they tightened down perfectly on our press frame. Solid hold so far.

Used a torque wrench on these for a critical jig assembly, and the 10.9 grade held up without any deformation in the hex head. The partially threaded shaft was exactly what I needed for a heavy clamping application.
