Anti Backlash Nut
I posted about this previously, this is what it looks like:

Anti Backlash Flange Nut:
I'm thinking of ways to incorporate an anti backlash feature onto the Dia 3/4" x .50" lead screw flange nut.
It might be possible to place a tapered pipe thread on the exterior of the Roton flanged nut with a NPT 3/4" die.
A tapered pipe thread would allow you to screw on a threaded coupler to compress the thread into the lead screw to take up the backlash.
Method:
Machine a lead in angle on to the Dia. 1.125" end so a 3/4" NPT die can fit over it.
Cut threads into the O.D. of the flange nut with a pipe thread die.
Cut 1 or more narrow slot down the center of the flange nut.
Remove all internal burrs. Thermal deburring might work, but I don't know what plastic it's made of.
Screw on a metal or plastic NPT bushing, coupler, reducer, etc., to compress the flange nut into the lead screw.
