براغي رأس سداسية M12-1.25 × 50 مم | فولاذ فئة 8.8 مطلي بالزنك | ملولبة جزئيًا (100 / عبوة)

The partially threaded design made it easy to start by hand before using a socket, and the zinc coating looks clean. I used these for mounting some heavy equipment and they bite securely without stripping.

Exactly the right thread pitch for my lathe tool post hold-downs, and the zinc plating looks clean without any burs. The partially threaded section helps keep alignment when tightening down.

I needed partially threaded M12 bolts for a heavy fixture build, and these 50mm ones worked perfectly with my socket drive. The zinc coating looks clean and even, which should help prevent rust in my shop.
