kh seat problems

my kris holm seat wiggles back and forth. i tried tightening the bolts under the seat, but the keep on coming loose. it looks like they’ve slid out of the place that they’re supposed to be in. how should i fix this?

you can use locktite. but all i use is lock washers. they seem to help me

Using those nuts with the ring of nylon over the thread (Ny-Lock?) solved the problem for me.
