The drawings call out masking the threads prior to powdercoat

@west this is true, however, we have heard that this is difficult and time consuming to manufacture for our suppliers. Not only that, but the method used to mask the threads is not always very effective. The idea here is that putting a masking dot onto every threaded hole on both sides is easier and more effective than putting in plugs. This is especially true for the holes that mount the bed washers, since they have a masking dot on one side and not on the other which makes it hard for the plug to stay in there during powder coating.

@kent i think the biggest issue with putting a masking dot on every hole is that the cosmetics will be negatively affected.
I see no reason that this would cause mechanical or electrical issues, however it could potentially introduce EMI/ESD issues.

I think either we pay the cost of chasing threads in house, or pay the cost of having our supplier plug the threads as they have traditionally done.

@jessica can you check with our supplier and see if this will help them?

@jessica already has checked and this changed would actually be painful, but they are looking into other options

Any idea why?

@kent I'm going to close this out as the supplier that this was originally discussed with will not be supplying metal for Quiver.
