براغي رأس سداسي داخلي M18-2.5 X 140mm | محرك سداسي داخلي | خيط جزئي | فولاذ سبائكي فئة 12.9 مطلي بالزنك (10 / عبوة)

Used a full set of these on a heavy jig frame and the 12.9 grade held up perfectly under high torque without any thread stripping. The zinc coating gives them a clean look and they came well-packed with no damage to the threads.

The partially threaded shank on these M18 screws made aligning my jig setup much easier than with fully threaded bolts. Zinc plating looks clean and the hex drive seated perfectly with no stripping.

I’ve been using these for a heavy-duty fixture build, and the partially threaded design made alignment much easier than fully threaded alternatives. The zinc plating has held up well in my shop environment too.
