Need some help. I need some advice and info on Pillar bedding a stock.

I built a cherry stock for my 110 but I want to install pillars.

Question is where do I get correct Stock screws and pillars. Found pillars at brownells and screws that are for a Rem 700 but I dont know if the head is correct. They need to be slightly longer than the stock ones?

Any help here?
