براغي رأس أسطوانية M16-2 × 40 مم | رأس زر بمحرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (50 / عبوة)

Finally found a batch of M16-2 socket cap screws that aren't all burred out of the box — the hex drive on these grabbed cleanly every time. Made quick work of a repair on a production jig at the shop.

Used a full pack of these on a custom jig for the shop, the 12.9 alloy steel feels seriously solid under load. The zinc plating’s held up fine so far with zero rust after a few weeks of coolant exposure. Threads cut clean into our tapped holes without any binding.

These M16 button head screws fit perfectly into my jig setup, and the hex socket drive made installation quick without stripping. The Class 12.9 alloy steel feels noticeably tougher than standard hardware I’ve used before.
