Just wanted to know if there was a differing SM screw mount also, so not to make mistakes...

Be aware though that there was a screw mount used by Pentax prior to the M42. It was called M37 and was used on Takumar lens from the early to mid 1950s.
Here is a history link> Early Pentax Takumar Lenses

While you probably won't encounter the m37 that often, its a good habit to refer to it as m42.
