My motto is to make lead mounting holes capable of allowing a fair
clearance around whatever size lead is to be fitted, not the minimum

any component on the board. One size doesn't fit all and if it means an
extra drill size then so what. It makes for easier component removal, if
needed, later on.

Snag is the most reliable solder joint is where there is minimum solder
infill.
