براغي رأس سداسية M16-1.5 × 130 مم | فولاذ فئة 8.8 عادي | جزئية الخيوط (25 / عبوة)

Used these to fasten a heavy bracket to a steel frame, and the 8.8 grade held up perfectly under torque. The 130mm length gave me just enough thread engagement without bottoming out.

The hex head fits my socket perfectly, and the class 8.8 steel feels sturdy enough for heavy equipment assembly. I've used a few already, and they thread cleanly without binding.

The thread engagement is perfect for bolting heavy equipment brackets where you need the grip on the shaft but full threads up top just won't sit flush. I've torqued a few of these to spec without a single one stripping, and the hex head takes a socket cleanly. No complaints for the price.
