براغي رأس أسطوانية M16-2 × 65 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 12.9 مطلي بالزنك (25 / عبوة)

The partially threaded design on these M16 screws made alignment in my jig much easier than fully threaded ones. Zinc plating looks clean and the class 12.9 steel feels seriously tough for heavy tooling work.

The hex socket drive seated perfectly on my torque wrench without any cam-out, and the 65mm length was spot on for aligning two thick steel plates.

Used them for a jig I’m building and the threading grabbed cleanly right up to the shoulder—no wobble or stripped heads even with a torque wrench. The zinc plating’s held up fine after a few days of shop dust and oil splatter, which is more than I can say for cheaper kits.
