براغي رأس أسطوانية M16-2 × 65 مم | رأس مسطحة بمحرك سداسي داخلي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (50/عبوة)

These things are seriously solid — the 12.9 alloy steel feels way more rigid than the standard bolts I usually pick up, and the zinc plating gave them a clean, uniform finish straight out of the bag. I used them to bolt down a steel jig plate and every single one threaded in smooth without any galli

The hex socket drive made tightening these into a jig frame so much easier than dealing with a hex key in a tight spot. The zinc plating on these M16-2 screws looks clean and consistent across all 50 pieces. Exactly what I needed for a precision assembly project.

Needed high-strength bolts for a custom jig build, and the fully threaded design on these let me adjust clamping depth precisely. The zinc plating looks uniform and should hold up well in the shop.
