براغي رأس مقبس M12-1.75 × 70 مم | محرك سداسي | جزئي الخيوط | فولاذ سبائكي فئة 8.8 مطلي بالزنك (50/عبوة)

The zinc plating on these M12s is holding up beautifully, no rust after a few weeks in the shop. Threads are clean and engage smoothly, and the 70mm length with partial threading gave me just the right bite for a heavy-duty fixture.

I was fitting some jig components together and these M12 socket cap screws seated perfectly with the hex driver. The 70mm length and partial threading gave me just the right bite without bottoming out.

The partial thread on these M12s makes them perfect for clamping thick plates without bottoming out, and the zinc plating has held up nicely against shop grime. Every screw threaded cleanly into my tooling fixtures right out of the package.
