Found the description **8mm** x 2mm pitch lead screw with POM nut. 42mm by 42mm nema 17 short size 23mm tall 4 wire I suppose I would like a 200mm shaft or so. Ideally I am looking for the exact thin motor we have but with a longer shaft. When I search for this I get thousands of hits that aren’t quite right. Is there something I am missing about online shopping for stepper motors? I am getting bogged down. It looks like I can buy a new longer shaft and there is a video that shows a guy breaking the glue that holds the shaft in place and then replacing it but it feels like there might be a better option. I can get clamps that would let me add the new screw to the end of the old one. That is cheap and might work.Matching 10mm linear bearing rod (300mm) is kind of expensive from grainger --- _[View the full topic](https://forums.maslowcnc.com/t/longer-z-screws-and-rods/25589)._
