@jwoody18 Jeff. I read somewhere on the Sienci site, either the home site or this forum, that the set screws in the acme nuts enter at an angle. The nuts are to be threaded on that so that the set screw angles outwards. This makes it easier to tighten and also ensures that it does not hit the bearing on the end of the acme rod. I think that it’s likely that your set screws were not bent. They just looked that way since they were on an angle to the nut.
