براغي رأس سداسي M12-1.25 × 100 مم | فولاذ فئة 10.9 عادي | ملولبة جزئيًا (175 / عبوة)

These bolts are rock solid in hand, the 10.9 steel has a good heft to it and the hex head grabs a wrench cleanly without slipping. Used them to mount a motor bracket and all 175 went in without a single stripped thread, which is exactly what you want from a bulk pack.

The partial threading on these M12 bolts made them perfect for clamping thick steel plates without bottoming out. They’re tough—my impact driver didn’t even flinch tightening them down.

I needed some heavy-duty bolts for a jig, and these hex head screws fit the bill perfectly—the 10.9 grade steel feels rock solid. The threads are clean and started easily in the pre-tapped holes without any binding.
