M10-1.5 X 140mm 六角頭螺絲 | 10.9級鋼鍍鋅 | 部分螺紋 (50/包)

Used these to bolt a heavy steel bracket to a concrete wall and the 140mm length let me get through the insulation without issue. The hex head took a socket easily and the zinc coating looks like it will hold up well in my workshop.

I needed a full 140mm length to reach through a thick bracket, and these class 10.9 screws handled the torque without any flex. The zinc plating looks clean and should resist rust well in my shop.

The partially threaded design was exactly what I needed for a custom frame assembly where I only wanted threads at the tip. The hex heads sat flush with my socket and the zinc plating looks clean.
