M20-2.5 X 190mm 外六角螺絲 | 10.9級鋼本色 | 部分螺紋 (10 / 包)

The hex heads on these bolts gave my socket wrench a solid, no-slip grip during assembly. The 190mm length was exactly what I needed for bolting down heavy equipment frames.

The partially threaded design made aligning these into my equipment frame much easier than fully threaded bolts. Torqued them down to spec with no issues—the hex head held the socket perfectly without stripping.

Used these to mount a heavy-duty steel bracket to concrete, and the partially threaded design let me get full engagement without bottoming out. The hex heads held up perfectly under a solid 200 Nm of torque from my impact wrench.
