The threadserts were the most difficult part of this installation. Not installing them, but finding the installation tool and threadserts themselves.
We first went to Lowes, Home Depot, and finally Ace Hardware with no luck. Eventually we ended up at a specialty nut & bolt store, but they wanted $50 for the tool.
Turning to the web, we started searching. I hate to admit it, but it was a ?Ricer? forum that led us to Harbor Freight where we could get the
Threaded Insert Riveter tool and aluminum threadserts as a kit for $15.
