براغي رأس أسطوانية بمسدس داخلي M22-2.5 × 140 مم | محرك سداسي | سنون جزئية | فولاذ سبائكي فئة 12.9 مطلي بالزنك (10 / عبوة)

Installed these on a heavy-duty jig I’m building, and the partially threaded design gripped perfectly under tension. The zinc plating looks clean and uniform, no burrs on the threads.

The partial threading on these M22-2.5 socket cap screws made a real difference when I was putting together a heavy jig for my shop. They drove in smoothly with just a hex key, and the zinc plating looks like it'll hold up well against moisture.

Used these to secure the base of a welding fixture, and the 140mm length was exactly what I needed. The partially threaded design made alignment much easier than a fully threaded bolt would have. Only complaint is the zinc coating could be a bit thicker for outdoor use.
