Typically, the thread on the top of the tripod column is a .375 - 16 tpi (3/8) and the wrinkles in a camera's bottom can be either the 3/8 - 16 or 1/4 - 20. Bushings are available at camera shops to screw in to the camera's mount to adapt the 3/8 thread to 1/4.

Were you speaking of the camera mount on a head or the tripod's connection?
