M20-1.5 X 35mm 六角頭螺絲 | 10.9級鋼 鍍鋅 | 全螺紋 (25個/包)

Fully threaded all the way to the head, which made cinching down a heavy steel bracket a lot easier than dealing with a partial thread. The zinc coating is smooth and evenly applied, and the 10.9 hardness really shows when you torque them properly. These feel like they'll outlast the machine they're

The hex drive gripped perfectly without stripping, even torquing these to spec on a jig frame. The zinc coating looks clean and should hold up well in my shop environment.

Used these to bolt down a heavy press in my workshop and the threads cut cleanly with no binding. The zinc coating seems to offer decent corrosion resistance so far.
