T8 8MM Nut Kit for Ender 3 / Pro Ender 5 CR-10 CR-10S POM Trapezoidal Screw Nut (All Hardware Included)
We have tested these on an Ender 3 and they are awesome!
Material: POM, This is a special engineering plastic material, common name is"Saigang" which is very close to the properties of steel,
It is better than brass for a lead screw. You can read more about POM Plastic at Wikipedi, see Polyoxymethylene https://en.wikipedia.org/wiki/Polyoxymethylene
Even PRUSA is using POM on their MK Series of 3d-printers.
Last but not least the holes are threaded and match the Creality hardware.
What is included:
(1) POM T8 Screw Nut
(2) Screws
(2) washers
NOTE: Some images show product installed on a T8 Screw Rod which is NOT included. I know I am repeating myself at least twice. Pease see list of "What is included" for what you will receive. I cannot believe I have to say this.
