براغي رأس أسطواني بمقبس سداسي M12 X 40mm | محرك سداسي | سبائك فولاذية فئة 12.9 (160 / عبوة)

Installed a batch of these in a heavy-duty jig yesterday and they torqued down evenly without any binding. The 12.9 alloy steel gives me real confidence for load-bearing fixtures around the shop.

The hex socket drive on these M12 screws fit my torque wrench perfectly, no stripping. All 160 pieces in the pack were cleanly threaded and consistent. Exactly what my jig assembly needed.

We build a lot of jigs in our shop and these cap screws have been spot-on—the hex socket drive grips cleanly every time, and the 12.9 alloy steel feels tough enough for our milling fixtures. The 160-count box means I won't be reordering for a while.
