براغي ذات رأس أسطواني M8-1.25 × 55 مم | محرك سداسي برأس مسطح | ملولبة جزئياً | فولاذ سبائكي فئة 10.9 مطلي بالزنك (100/عبوة)

Installing these into a jig fixture I’m building, the threads caught smoothly and the zinc plating looks tough enough to resist shop grime. The 55mm length is perfect for clamping through a thick bracket without bottoming out.

The hex socket drive sits deep and clean, so my 6mm Allen wrench grips every one of the hundred without any stripping. The 10.9 alloy steel feels properly hardened too, thread engagement in my jig frame was solid. Exactly what I needed for the tooling rebuild.

The zinc plating is holding up nicely after a week in a damp workshop, no rust spots yet. These M8s cinch down clean with a 5mm hex key and the partial thread gives just the right grip for my jig builds. Exactly what I needed for the tooling rack.
