4 drain plug screws, with o-rings, for Keihin carburetors on the Honda CB350 CB400F, CB550, CB750 and many others. If you've got a leaky drain plug screw and the threads on the float bowl are intact, you might just need a new o-ring. But wouldn't it look nice to have all new shiny drain plugs! Sometimes it's tough to track down the right size o-ring, so here's a complete plug screw ready to install! People have a tendency to mangle the heads on those drain plug screws due to over tightening them trying to stop the leak, this forces the next person to wrench on it to get it off, don't be that guy!
Includes 4 drain plugs with o-rings

Perfect replacement
Used on a CB350F. Perfect fit. Good to have drain screws that don't have mangled slots. Much easier to remove now. Thanks!

no more leaks
Used them on my Honda CB500 four. Although the 500 was not on your list they fit perfectly and no more leaks.
