This question comes up often enough that it deserves it’s own topic. I’ve assembled what I know here. Please feel free to fill in the blanks for other models and manufacturers and I will update the main post as they are added. Only add an entry if you are sure about it please.
This should help when people need to replace an axle and may be able to find what they need at a hardware store. If you don’t find it here, take your yoyo to the hardware store and see if they have something that fits i.e. proper thread size and length.
Note that if they don’t have the right length, get a screw of the correct thread size and cut it to length. Smooth the cut edge with a fine file or coarse stone.
