براغي رأس سداسية M16-2 X 130 مم | فولاذ فئة 8.8 عادي | ملولبة جزئياً (25 / عبوة)

Was a little worried about fit but the M16-2 thread pitch is spot on, and the hex head grabs a socket without slipping. Used them to bolt a motor mount, they held tight under vibration.

The partially threaded design made installation on my machine frame a breeze, and the hex head gripped perfectly with my socket wrench without slipping. These bolts feel solid and hefty, exactly the quality I expect for heavy-duty equipment assembly.

These were exactly what I needed to replace the worn bolts on our press; the 8.8 grade steel feels reassuringly solid. The partial threading gave just the right grip depth for our heavy flange setup.
