If you don’t like the standard ring nut that comes with your round type ignition switch, here’s your quality alternative. Hex style flange nuts which are CNC machined from stainless steel. Now you can tighten your switch down with a spanner so it won’t shake loose after a few miles down the road. A drop of thread locker doesn’t hurt though.

Use this spanner to securely tighten or loosen the special ring nut that comes with your round type ignition switch. A great alternative to pliers which will inevitably scratch your nut.
