There was Proto-Uralic piŋз "hand, palm": https://en.wiktionary.org/wiki/pivo#Etymology_2
I wonder whether it was related to the PIE words.

I am unaware of any relation between the two that stands on solid ground, but there is a decent amount of loanwords between the two languages.
However, on the extremely speculative (read: controversial) side, there are a few theories that do relate those terms. Proto-Indo-Uralic and the notorious Nostratic theory both relate the terms.
In entry 1068 of the Nostratic Dictionary (2012) by A. Dolgopolsky, he lists:
PIE - *de-kmt "ten" from *dwe "two" + **komt "hand with fingers"
U - *käme(ne) "palm of hand"
amongst many, many others. Under the entry for "finger" lists similar derivations that include *pénkʷe.
I apologize for the transcription from the dictionary, the text is littered with a myriad of non-IPA symbols of his own invention, so I didn't even bother with them.
