What screws to use for my wood window balance

A home owner from Madison says:

I've got wooden doublehung, non-tilt windows that I am pulling out and re-glazing/painting. The spiral balances on them aren't in great shape, some better than others. I've got it figured out that I need 21" & 23" 500 series spiral balances and I know which brackets I need. My question, is what screws should I use for mounting the balances and what screws for the brackets?

I like to use our 33-017 screw to install the balance tube at the top and our 33-090 for the sash brackets at the bottom. You can use these, or something you have on hand that's the same size.
