براغي رأس سداسي M16-1.5 × 40 مم | فولاذ فئة 10.9 عادي | ملولبة بالكامل (200 / عبوة)

The threads are cut clean and the 10.9 steel feels properly hardened, no galling or burrs on any of the 200 pieces. I used them to bolt down a heavy motor mount and they torqued up smoothly with no wobble.

These M16 bolts are exactly the right thread pitch for my tractor attachment rebuild, and the hex head grips the socket firmly without stripping. The fully threaded shaft gives me plenty of bite into the threaded hole I tapped. Pack of 200 should last me through several more projects.

Used these to rebuild a press table at the shop and the hex head grabbed nicely with a socket, no stripping. The 40mm length was just right for our application, though the 200 pack left us with nearly half leftover. Solid fasteners for the price.
