Half the bits are imperial! What the hell are they selling those for?
My first car was made in 1988, and even that was metric for goodness
sake. I guess half of it's going on freecycle for vintage car owners.

Still plenty of new stuff being sold using imperial. New rotary lawn
mower - the bolt that holds the blade on has a 9/16 inch head.
I expect if it has a Briggs and Stratten (USA) engine it will be all
imperial.

I've never had to use an imperial socket bit. Perhaps if you have every size (each mm), then one will always fit. Being 0.5mm out probably still fits good enough.

Your mower would be 14.2875mm then. I assume you can't quite get the 14mm socket bit onto it? I guess 0.75mm too big would maybe jump.

I'm really surprised your mower is imperial though. What make is it and why are they in the wrong century? Bloody hell my first car was a (British) 1988 Rover, and even they used metric bolts.
