MO, i believe they are 21/64". I'm pretty sure (someone correct me if I'm wrong)that the 21 is the diameter and the 17 means the wall thickness is .017" Hope this helps.

Ok. I guess I better clarify my question. Which size of the gule on type nocks that fit a swaged end will fit a 21XX shaft? I guess the 11/32" since its slightly larger than a 21XX diameter sized shaft.

If you have access to a saw, I'd STRONGLY recommend you cut that swage off and put in uni bushings.

2117 = 11/32" or 5/16" shaft?
