براغي رأس سداسي M12-1.25 × 40 مم | فولاذ فئة 8.8 مطلي بالزنك | ملولبة جزئيًا (75 / عبوة)

Zinc plating looks clean and uniform across all 75 pieces, and the partially threaded design gripped perfectly when I torqued them down on a steel frame. Class 8.8 held up without any stripping.

Installed these for a heavy-duty jig build and the partial threading made alignment much easier. The hex head seated cleanly with a socket wrench and they held up to some serious torque without a hint of stripping. Good value for a 75-pack, especially with the zinc coating.

I needed hex head screws for a machinery assembly project and these 40mm ones fit the bill perfectly. The zinc plating on the class 8.8 steel looks even and should resist rust in my shop.
