Clam Thermal X - Seat Bolts Lossening?

[lazyMlazyK]

Hi all, long time lurker, not real active poster.  Have a question for you all...does anyone else with the Clam Thermal X have issues with the bolts in the seat swivel loosening and falling out?  I've got a couple to replace and I think I'll try putting locking nuts on this time.  I picked up the shack used last year and this is my first flip over.  Had two other homemade portables and this is a huge upgrade!
