M8-1.25 X 75mm براغي رأس أسطواني | رأس زر محرك سداسي | ملولبة بالكامل | فئة 12.9 سبائك فولاذية مؤكسدة سوداء حرارية (100 / عبوة)

Used a few of these for securing a heavy jig on my mill table — the 12.9 alloy steel held up perfectly under torque without any sign of stripping. The hex drive seated cleanly in my allen key, and the fully threaded length gave me exactly the grip I needed.

The black oxide finish on these is flawless—no flaking even after torquing them hard into my fixture plates. Threading was smooth all the way down the full 75mm length, and the hex drive seated perfectly. These are going straight into my regular rotation.

Installing these in my latest jig build was a breeze with the hex socket drive—no cam-out issues at all. The 75mm length was exactly what I needed for clamping thicker workpieces together.
