Stick hardware question

the screws&nuts that hold the moutning plate for my stick keep getting loose, causing the mounting plate to slide around during play.
does anybody have any secrets to prevent this from happening?

some nuts and help from a friend named Bruno.

If the nuts and bolts are coming undone, get locking washers from Lowe’s/Home Depot or such.

If the bolts and nuts remain tight, but there is play in the holes; well that gets a bunch more complicated.
