I can't seem to get smart fasteners to work on these 3 parts. It's a plate with threaded holes and 2 clamping brackets with clearance holes. I can only see to get it to work with one clamp at a time. I can select a clearance hole on each clamp separately and adjust the length but I'd rather not do that. Is it possible to this with the all threaded holes on the big plate and the clearance holes on the clamp?
