A 2x4 just got in between my carriage and bumper stop on my new Nema 34 R&P and snapped.the pivot bolt before I was able to react and hit the E-stop button. I am trying to find a replacement to get me back up and running as quickly as possible. Does anyone know the specs of the pivot bolt? From CNCRP's site, I see that it is a 3/8-16 thread, and measuring the shoulder it appears to be 1/2" dia and 2" long. Is that correct?
