Thanks guys! I hope this helps a few of you. Chris - I didn't use the thread locking spring plungers. Either style should work fine though. I just torqued the nut down tight so it won't vibrate loose.
By the way, if you're ordering from McMaster Carr from Canada, you will need to order through a business. They rejected my order initially, even with a US shipping address. I found that annoying, but I couldn't find the spring plungers anywhere else.
Slightly unrelated - I purchased new Kason door hinges for my Trillium
from McMaster Carr earlier this year. I found the info in an old thread on this forum. They don't show the hinges on their website but when I entered the part number it allowed me to order them.
