M10-1.5 X 200mm 六角頭螺絲 | 10.9 級 鋼 普通 | 部分螺紋 (15 個/包)

Was able to torque these fully into a steel frame without any stripping, the 10.9 grade really holds up under pressure. Threads are clean and the partial threading made alignment much easier for this job.

I needed these for a heavy machinery frame, and the 200mm length was just right to reach through multiple flanges. The hex heads let me torque them down securely with a socket, and all 15 screws were undamaged with clean threads.

The partially threaded design made seating these perfectly in my jig setup, and the 10.9 steel feels properly tough under a torque wrench—no stripping or flexing at all. These are exactly what I needed for the 200mm reach.
