I’ve used 11mm on the brake caliper bleeder nipple.
My vote is for 18mm. I’ve probably used it but can’t think of a time I did.

I voted 11 however I leave one on my workbench out all the time as I do use it often enough.
The 16 and 18 are used on the suspension of my 718 as well as my R32. My beetle uses 10/13/14/15/17/19. The 11/12 is used randomly on those vehicles but to a lesser extent. My Toyota 4Runner uses 12 somewhat commonly, hence the 11 was the short straw.

I'm actually surprised 11 hasn't gotten more votes. Maybe it's just the cars I own, but I can't remember using an 11mm wrench in a very long time.J-Dub wrote: Fri Aug 07, 2026 4:30 pm I voted 11 however I leave one on my workbench out all the time as I do use it often enough.
