🔧 Enhanced NW Length Backlash Spring Loaded: Uncompromising Performance and Reliability Review

These were straight leadscrews, they didn't oscillate. I used two Z axis motors in my Hypercube Evolution 3D printer. The anti backlash nut is a bonus at this price point. It's not Misumi quality, but they work damn well.

Brass nuts seem to be ok. They squeak when installed properly and the spring is fully loaded (no problem, just needs some lube). However, the two bolts I received had a lot of burrs on the threads, almost like spatter from a nearby weld. Some of them have been scooped out with my fingernail, and for others I have to use a wire brush (I hope the wire brush works). I'm not sure how long he can keep up with these bugs before eating the nut inside.

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.
