براغي رأس سداسي M8-1 × 35 مم | فئة 10.9 من الصلب العادي | ملولبة جزئيًا (1000 / عبوة)

These hex bolts torqued down perfectly on my jig fixture without any stripping. The class 10.9 steel feels much tougher than the standard hardware I usually pick up. Nice to have a full box on hand for future projects.

Installed a whole set of these on a new conveyor assembly at the plant and they drove in smooth with zero cam-out. The partial threading made alignment a breeze when stacking multiple plates. These M8-1 x 35mm hex heads hold tight at 10.9 grade.

Packed a whole machinery frame with these and every one seated perfectly into the tapped holes without any stripped threads. The partial threading gave just enough grip for heavy plates.
