براغي رأس سداسي M12-1.75 × 100 مم | فولاذ فئة 8.8 عادي | ملولب جزئيًا (50 / عبوة)

I needed a solid fastener for a machinery bracket, and the partial threading on these made alignment surprisingly easy. They gripped tight with a standard 19mm socket, and the 50-pack means I've got spares for future projects.

The hex head on these bolts gave my socket a solid grip without any slipping, and the 100mm length was exactly what I needed for a mounting bracket. Threaded smoothly into the pre-tapped hole and held tight with no wobble—just what you want from a class 8.8 fastener.

Used these to secure a heavy jig onto a milling table, and the 8.8 steel holds perfectly under constant vibration. The hex head drives cleanly with a socket, no stripping or rounding. Exactly what you want for industrial gear.
