براغي رأس سداسية M20-2.5 × 30 مم | فئة 10.9 فولاذ مطلي بالزنك | ملولبة بالكامل (25 / عبوة)

Had to torque these down pretty hard on a steel fixture, and the zinc plating held up without any stripping. The hex head gave me a solid bite with my socket.

Used a full package of these to bolt down a heavy press at the shop, and the zinc plating held up fine against the grime. The hex heads grabbed perfectly with a socket, zero stripping even on the last few. Class 10.9 is no joke—these feel solid and torqued down without any give.

Threaded all the way, these M20 bolts grabbed evenly from the first turn, and the zinc plating looks clean and consistent across all 25 pieces. Used them to secure a heavy steel bracket—held rock solid with no stripping.
