i have a qr system 6 seatpost. where the post attaches to the seat are 4 vertical screws - 2 on each side. they are about 1/4 inch wide. what do they do, because as i was riding 2 fell out. I had a test seat put on so wondering if it wasn't secure. This is a very ignorant question, I know, but I cannot find anything online on what they are and how to fix.
