براغي رأس سداسية M12-1.75 × 55 مم | فولاذ فئة 10.9 مطلي بالزنك | كاملة الخيوط (275 / عبوة)

Installed these on a heavy-duty jig I was building, and the hex head grabbed perfectly with a socket wrench every time. The zinc plating seems solid, no rust after a few days in a damp shop.

The fully threaded design made these easy to drive into steel brackets without stripping. I just wish the packaging included a few extras in case one gets dropped.

The zinc plating on these screws is holding up well even in my slightly damp workshop. They threaded smoothly into pre-tapped holes on a press fixture I'm rebuilding, which saved me time. Only minor gripe is the lack of a thread-locking patch, but that's standard for this type.
