Review on Threaded Backlash Elimination Kit by BIGTREETECH Direct by Chris Wheeler

I'll start by saying the nut is well made and still good value for money but. The screw holes are M3.5, or more like #6 (between M3 and M4 I think), which is an odd size that even people with a 3D printer probably won't be sitting around with. It would be nice if they included screws because of this. I ended up using M3 bolts from below and nylock nuts from above. Works great, can't say it's a kludge but it annoyed me that I couldn't easily recycle the original bolts (took longer to accommodate the nuts). The M3 hardware is lying around, keep that in mind. I'm also not sure why it's being sold as a four pack. I'd happily pay the asking price ($9 at the time of this review) for just a nut or two with play if they include the bolts.
