Can someone tell me what the API spec number is that details the dimensions for drill pipe threads? Specifically, I am looking for dimensions for API Regular threads.

Thank You
 
API Spec 7 "Specification for rotary string elements"

API Spec 5B "Specification for threading gauging
inspection of casing tubing and line pipe threads" (in case you've got 8 round thread instead of IF or REG threads

API RP 7G "Rotary shouldered thread connections: working limits" will tell you the performance of different threads and their interchangibility.
