Think they came with a wing nut. It´s easier an faster to open but..Not sure if the FJ45LP-B and FJ55 may be a little different. Remember both of mine have a wing nut. I remember pulling one from a FJ55 in a wrecking yard and the other was bought off eBay. Can't remember how that one was listed.

....not abnormal that wingnuts did not want to turn and then one or both wings break.
Then you use instead of a wing nut a normal nut.
Who has a spare wing nut ?... nobody.
And who buy 1 new wing nut? ....nobody.. you use a normal nut instead... that´s normal.
