براغي ذات رأس أسطواني M16-1.5 × 60 مم | محرك سداسي | ملولبة بالكامل | فئة 12.9 من الفولاذ المخلوط مطلي بالزنك (25 / عبوة)

I needed some high-strength fasteners for a jig I’m building, and these M16 bolts fit perfectly. The 60mm length gives just enough reach without being cumbersome, and the hex drive made installation a breeze.

The zinc plating looks flawless on every single screw, and the 12.9 alloy steel feels rock solid when I torque them down. The fully threaded shaft grips cleanly in my jig setup, no binding at all.

I used these for a heavy-duty fixture at work, and the 12.9 alloy steel really holds up under torque—no stripping issues at all. The hex socket drive makes install quick with an Allen wrench, and the zinc plating looks clean.
