Neck finish specifications

[mgnt8]

Sorry for the double post - maybe this is the better place to ask the question:

Does anyone know where the closure thread finish specifications are maintained these days? It used to be the SPI. Then it was the CMA. Now I believe the CMA rolled over into the CCMA, but they don't have the closure specs anymore.

I found the bottle neck finishes on ISBT's threadspecs.com, but they have no caps.

Any help is much appreciated.

mgnt8,

I have attached a copy of standard sp400 neck fininshes. Closures are almost all diffrent by manufacture. I always go to the customers supplier of caps and build my neck to match their spec that way no liability when cap dont fit if your neck is in spec
