Thread is giving me safety wire PTSD from my Air Force days... I've strung miles of that stuff. Admit I still have a pair of safety wire pliers in my toolbox... lol.
If you've ever raced things at lots of national level road course events, you are very familiar with those pliers as well. I have a set in my toolbox from racing and crewing on all sorts of stuff.
Nice work, haven't seen those bolts come loose myself. Always a first time.
