Yes.
If the fuse to fuse holder contact clips are not holding the fuse end caps tight remove the fuse from the fuse holder and carefully squeeze the fuse holder clips together using a pair of needle nose pliers. Carefully, you don’t need much. Reinstall the fuse and check if the connection at each end of the fuse is tight.
As for tightening the connections at each of the fuse holder. Do not over tighten.
