It's probably the sort of thing that will require more frequent re-tensioning.
Spring washers or Nyloc nuts won't deal with the heat. K nuts or Jet-Nuts might be an option but due to the very cramped access winding a locking fastener on half a flat at a time with a bent spanner, my tongue out trying to do it isn't my idea of fun.  |
Dougy knows what hes talking about. Its a very hard access point and this has been the first time that this has happened since it was installed a good year ago. So I dont think its a problem of the fasterners just bad luck. Its an easy although time consuming fix, but is only minor in the grand scheme of things.
