قضيب ملولب حركة خطية 12 مم بطول 1 م

The rolled finish is noticeably smoother than cheaper cut rods, making the nut glide along with almost no binding. It's exactly what I needed for my CNC Z-axis build.

For a 1-metre threaded rod the threads are surprisingly clean and consistent, making it easy to slide a nut along the entire length. Used this to replace a worn-out part on my 3D printer's Z-axis and the movement is noticeably smoother now. Really happy with how straight it is for the price.

The rolled finish on this 12mm rod is noticeably smoother than a standard cut thread, so my nut glides without any binding. Cut to 1m, it’s exactly what I needed for a solid Z-axis on my build, and the right-hand thread matched my motor coupler perfectly.
