براغي رأس سداسية M27-3 × 300 مم | فولاذ عادي من الفئة 10.9 | خيط جزئي (10 / عبوة)

The partially threaded design made torquing these down on a flange assembly much easier than fighting full-length threads. Head sits square and the 10.9 rating feels solid under the wrench.

These things are absolute units. The thread engagement on the partially threaded section was precise and the hex head fit my 46mm socket perfectly for torquing down our press frame.

I wasn't expecting these to be this hefty, but the Class 10.9 steel feels rock solid and the hex head grips perfectly with a socket. Used them to secure a press frame and the 300mm length gave just enough thread engagement for the job.
