The threads look like modfd. acme to me ( 28-29 degree kind).Tommy-D said:> If I'm not mistaken,Cue-Tec uses a 3/8-14 thread,but that one looks a little off. For the cuemakers that use the typical modified Acme pins,how do you check the thread depth on these,with thread wires the same way you do a 60 degree v-thread? Tommy D.
