Loctite 243:
As much as I'd like to provide a handy link to buy Loctite, Amazon's supplier system simply isn't trustworthy enough. My best advice is to read the manual for your specific Equipment and go to a local hardware store to pick up the right kind. I'd recommend thinking about multiple bottles, both a home size, and a travel size. It doesn't take much, but if you change feet frequently, it's just handy to keep available everywhere.
