Replacement for Honda Tool 07908-4690003 MAKE SURE YOU MEASURE YOUR LOCKNUT AND COMPARE TO SPECS SHOWN HERE! This tool does not fit every locknut known to man. Do your homework and measure yours first - and compare! This one simple step will save you much time and effort. See specs in photos and compare to your application if you are unsure of fitment. I cannot stress this enough. Impact drill is NOT recommended when using tools like this. Lubricate the threads thoroughly prior to use. A breaker bar might be helpful for difficult jobs. This exact size is very hard to find. Most dealers do not offer it. Items that were used are not returnable (unless they failed/broke under competent use.) If you return an item that was clearly used (yet you state it was "not needed" or "accidentally purchased" or other reason) you will not receive a full refund. Please note this very fair policy.
