I just got this one a few weeks ago off Amazon and it fit. Mines a V1. I don't know if V2 takes the same size.

Micro Swiss Plated Wear Resistant Nozzle for Creality CR-10S Pro/CR-10 MAX Original hotend ONLY (M6x.75mm Threads) .6mm https://smile.amazon.com/dp/B07NF7B1ZX/ref=cm_sw_r_apan_glt_fabc_12NHD73ZFTN5CDPZAYEZ?_encoding=UTF8&psc=1

Creality CR-10S Pro + v2/CR-10 MAX use a different thread: M6x.75mm. Most nozzles will not fit the original hot end, you can go with

MicroSwiss: https://www.amazon.com/gp/product/B07NF7B1ZX/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 (this is the most expensive route, and they have .4, .6 and .8 varients)

or Creality official, that ship from China, so might take longer to arrive: https://www.creality3dofficial.com/products/official-creality-cr-10s-pro-cr-10-max-nozzle-3pcs-0-2-0-4-0-6-0-8-1-0mm

I have a Pv2 and use the .6 MicroSwiss one. Good Luck!
