براغي تثبيت بنقطة كوب M16 × 80 مم | فولاذ سبائكي مطلي بالزنك (25 / عبوة)

Used these M16 set screws to secure a heavy-duty fixture and the cup point tip really bit into the metal without slipping. The zinc plating held up well during install, no scuffs or chips. Exactly what I needed for a tight-space adjustment.

The cup point bit into the metal firmly without slipping, and the zinc coating looks like it'll hold up well. These screws feel solid and the hex drive let me get them torqued down properly in a tight spot.

I was worried about stripping the hex socket under high torque, but these held up perfectly on my jig fixture. The 80mm length gave me exactly the reach I needed, and the zinc coating looks clean.
