براغي رأس أسطوانية M24-3 × 120 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 12.9 مطلي بالزنك (10 / عبوة)

The hex socket drive was the main reason I picked these, and it makes installation much easier than with a regular hex key. The zinc plating looks clean and should hold up fine in my jig setup.

Finally found some M24 bolts that actually hold up in my press fixture without stripping. The zinc coating is smooth and the threads cut cleanly into the tapped holes. Exactly what I needed for tooling work.

Installed these in a heavy-duty jig I'm building, and the 12.9 alloy steel gives me real confidence under high torque. The zinc plating has a nice, even finish that should resist rust in the shop.
