I have liquid force alpha bindings and the tighten down knobs on three of them are turning hard but not lossening. I can also turn them to tighten them but they dont ever stop. Are they stripped??

does anyone else have these, by the way they are on a PS3

The bolt is not stripped, its the plastic covers over the bolts, you will need to use pliers to pull the plastic covers off the bolts so you can get the bolts tight or to take them off.
