Befenybay 6PCS Diameter 8mm Black TR8x2 Lead Screw Nut for CNC and 3D Printer Parts (Size: Tr8x2)

Very solid and tight threads. Barely any play along the t8 rod. No lubrication needed and very quiet in operation. I have known delrin to be a very strong polymer - not easy at all to wear and cut but using this material makes the most sense to make contact with metal.

For the pitch specified, these are great bang for the buck. Slapped 2 of them right onto my Anet A8, but I had to drill new holes for the Ender 3. Cest la vie, cant keep it cherry forever.

These make a good update to help eliminate the need for lubricant and eliminate noise. They are a little sloppy - a lot like the brass ones. I think a little higher precision would be ok.

My ender 5 plus was driving me insane till I used these. Its so much better now, no more squeaks!

Super quiet, barely any play compared to brass nuts. These fit my 3d printer perfectly. Z movement is not loud at all. I hear the motors themselves way more clearly over the lewdscrew nut.

Worked!

Sadly these are 22mm not 25mm as required for prusa. Size should be specified in description!

Good item

I used these to replace the worn brass lead screw nuts on my Anycubic Mega X. They are perfect fits, and a little quieter than the originals. I do recommend that you put some lube on the lead screws to minimize wear, but that would be for nay lead screw nuts.

The threads on this fit the Prusa MINI+ and my first few prints have been successful. Although the threads fit, the fastener holes and diameter are not the same size as the MINI+s original nut. I had to modify the holes on this screw nut in order to fit the MINI+ (I cut it to make two of the holes into slots). So far it works!
