براغي رأس كبسولة M8-1.25 × 16 مم | محرك سداسي | ملولبة بالكامل | فئة 12.9 من سبائك الصلب مطلية بالزنك (200 / عبوة)

Used these on a custom jig I'm building for my workshop and the 12.9 alloy steel feels noticeably tougher than the generic hardware store stuff. The threads are clean and the zinc coating seems even, so they should hold up fine in a slightly damp environment.

The hex socket drive on these screws grips the driver bit perfectly, making them a breeze to install in my jig. The zinc plating looks clean and uniform across all 200 pieces.

These are exactly what I needed for my precision assembly work — the hex socket drive makes it easy to get them tight without stripping. The zinc coating looks clean and uniform across all 200 pieces.
