If you don't have enough collars of the right size (We never thought to check for ALUMINIUM collars, steel would have been overkill for our application) you can also take some aluminium rod stock, drill+broach the hex into it, and then file a flat to drill and tap! Worked great for us and get us the lightweight piece we needed.
