براغي رأس سداسي M12-1.25 × 40 مم | فولاذ فئة 10.9 مطلي بالزنك | كامل الخيط (50/عبوة)

I needed these for a repair on a heavy piece of equipment, and they threaded in smoothly with a socket—no cross-threading or stripped heads. The fully threaded length gave me plenty of grip for the nut.

The zinc plating is holding up well so far, no rust after a few weeks in a semi-damp garage. These pulled together a heavy equipment frame without a single stripped thread, and the 10.9 steel really feels solid under the socket.

Finally found the right length for a stubborn machine base repair — the 40mm fully threaded grip gives me exactly the bite I needed. Zinc plating looks clean and no rust after a week in a damp shop.
