Using these for the oil drain plug on my Yamaha XJ750. Most drain plugs have a crush washer that should be changed every few times (some say every time) you change your oil, with these I can inexpensively change the washer as needed. Works great, cured a leak caused by a worn out crush washer, and also reduces the force needed to get a good leak-free seal.
