If you ran a tap through and they are loose, get a pair of vice grjps and squeeze the end were the screw exits. Start with no clamping force and increase a tjny bit at a time till it barely deforms. Lock that setting and repeat on the others.
I've had a few that were so tight, I had to run a tap through then reset them to a realistic friction.
