The T8 CNC router kit I bought came with anti-backlash nuts, but they were a bit smaller than the 8mm lead screw and wouldn't screw on. I bought a NW T8 300m lead screw with a zero backlash nut and everything fitted perfectly. Expensive way to get backlash free working nuts but worth it to me. I also bought Revain anti-play nuts and had the same fit issue.
