براغي رأس كبس مقبس M16-2 × 75 مم | رأس مسطح محرك مقبس سداسي | ملولب جزئيًا | فئة 12.9 سبيكة فولاذ مطلي بالزنك (25 / عبوة)

Installed these in a jig fixture at work and the partial threading gave the exact grip length I needed. The zinc coating looks uniform and they seated perfectly with a standard hex key.

The hex socket drive on these M16 screws fits my torque wrench perfectly, and the zinc plating looks clean and corrosion-resistant for my jig setup. Partially threaded design held tightly in a machinery repair without any stripping issues.

The partially threaded design made installation into my jig much faster since the unthreaded section slides clean through alignment holes. I’ve used them for three heavy-duty fixture builds now and none have loosened or stripped.
