board house software packages like the odd spacing.

50 mil spacing isn't odd at all unless the design grid is set to 100.

If you can change the grid, place your parts at 100, then change to 50
(or 25) for routing.

If not and you can top-solder the H Bridge pins, you could make the
pads oversize or use Copper to place fake pads where you want the off-
grid holes, then drill them manually.
