So there I am with a pack of M12 flange nuts and lots of threaded rod, and I need an 18mm spanner... Except the first set I try goes from 17mm to 19mm, so I look at my socket set, same. Another socket set, same. The deep socket set included with the pneumatic impact wrench, same again! Had to use an adjustable in the end!

Didn't you have an 11/16"? If loose it may fit. I have come across a few 18mm bolts on Japanese cars.

So what's wrong with 18mm spanners?

My spanners are mostly Britool or Elora and I have never broken one. Most professional mechanics seem to favour Snap-on these days.

Snap on are dreadfully over priced.They're flogged by reps to apprentices with the carrot of paying by instalments. Prefer Teng for 'Good'ones but am happy with el cheapo 24mm and over when I will have only occasional use.

I do have one snap on 14mm spanner left in the engine compartment after a service
