براغي رأس كبس M16-2 × 65 مم | رأس مسطح محرك سداسي | خيط كامل | فولاذ سبائكي فئة 10.9 أكسيد أسود حراري (50/عبوة)

I needed some heavy-duty bolts for a machine jig I was building, and these fully threaded M16 screws held perfectly under high torque without stripping. The black oxide finish also gave them a nice, corrosion-resistant look that matched my tooling setup.

The hex socket drive made tightening these into a tight spot on my tooling jig much easier than using a standard wrench. The black oxide finish seems durable and hasn't chipped during assembly. These feel solidly machined and should hold up well in precision work.

Installed these on a heavy-duty jig I’m building, and the hex socket drive made tightening them down with an Allen key really easy. The 65mm length fit perfectly through multiple layers of steel.
