براغي رأس سداسية M16-2 X 90mm | فولاذ فئة 10.9 مطلي بالزنك | ملولبة جزئياً (25/عبوة)

Used these for mounting a heavy gearbox on a press frame, and the partial threading really helped with alignment before torquing down. The class 10.9 rating gave me confidence they'd handle the load without stretching.

The zinc plating looks clean and even across all 25 screws, which is nice for outdoor machinery. I used them to rebuild a press frame, and the hex head grabbed the socket wrench perfectly with no rounding.

The partial threading on these M16-2 screws made aligning the machine frame way easier than dealing with fully threaded bolts. The zinc plating looks uniform and they drove in smoothly with a wrench, no binding at all.
