I do the same thing as you Mowerfreak, except with a ratchet and an adapter to take the little hex bits - Phillips 3 sounds right - I never look at the numbers
I'm not versed in the number codes of different Phillips out Pozi heads, but this is what it says on the socket concerned and it was a perfectly snug fit on these particular Victa starter/ dress cowl retaining bolts and that is important as you don't want to damage the head from slippage trying to get these off!
