براغي رأس سداسي مقاس M12-1.25 × 40 مم | فولاد فئة 8.8 عادي | ملولبة جزئيًا (300 / عبوة)

These bolts fit perfectly in my industrial jig where I needed a strong, partial thread for clamping. The hex heads grabbed cleanly with a socket wrench and the 8.8 steel feels plenty tough for the job.

I needed a batch of partially threaded bolts for a machinery repair, and these 40mm M12s worked perfectly. The Class 8.8 steel feels solid, and the hex head seated nicely with my socket.

The hex head on these M12 bolts fits my socket perfectly, making installation on a jig frame quick without stripping. The 8.8 steel has held up well under moderate load without any visible deformation. A solid choice for general industrial fastening.
