A left handed one? 
I've been meaning to reply to this one...Years ago I was working nights and for whatever reason I had to work a late shift, 2pm~10pm. One of the blokes was setting a vertical machining centre with a Heidenhain control and the job required a left handed thread.
I was busy setting my own job but could see he was struggling as other blokes were wandering over to look at his program but he was still running the job in fresh air, ie not cutting material. Once I was up and running I offered to help and he explained he couldn't get the spindle to run anti-clockwise to tap left handed despite using an M04 in the program.
I asked him to show the tapping cycle and before he saw what I was doing I'd rewound the program, called up the tap and had the machine tapping left handed.
He asked what I'd done and I refused to tell him on the grounds that if he knew that he'd know as much as me,,,
He then checked the program and couldn't see what I'd done so asked again... Once again I refused to tell...
About two hours later it was almost time to go home so I finally relented and showed him which line I'd altered to tap left handed and he still couldn't see it so I showed him the exact piece of code I'd changed.
'How the f
k did you know that?'My reply of 'I was bored last night so read the manual for want of anything better to do' was not well received
Apparently they had been on it for over an hour, and I'm the mechanically ignorant spark.

10,000 posts and here I am posting about bolts. Whats happened to me, I used to get out and have real friends and a life.
Anyway, M10. There you happy?
(its the only one I can tell what size spanner/socket to use!)
That’s quite a big spanner size is that I tend to go for the more manageable up to sort of 14mm 9/16 area. Anyway, M10. There you happy?

)Here's quite a nice Stub Acme for the thread deviants, nice blunt start too.
If I'm in the garage, I tend to keep it real with an M8.
At work, especially on nightshift, it's a case of bigger is better*, especially as 99% of the time we thread mill rather than tap, which can lead to a decent runner, just the ticket at 2am!

- Unless the thread needs chased with a tap - a 3" UN isn't easy
.
This takes me back. I just reached into my bottom desk draw to find I still have some Thread Porn

13mm every time.
It's almost 1/2" so you can use either spanner
This, if only every thread was this size.It's almost 1/2" so you can use either spanner
Very wet and windy December night back in '98 (possibly boxing day) I was driving my Sierra down Cairney Brae on the A9 when a very recently fitted Halfords wiper fell apart, on the drivers side, of course. Struggled another 20 miles to Balhaldie services & as I inspected the offending item the driver of a Mk2 Golf GTI offered me a 13mm spanner & said "you'll need this". Now, I don't know if most wiper spindles are half inch or the guy was a mechanic but it remains one of my luckiest motoring happenings. Swapped the arms over & returned said tool to the VW man as he returned from the shop, then pressed on to Stirling with "Do The Hustle" playing on cassette, fun times.

A 13mm spanner will fit on a 1/2" bolt head, but will be so slack as to leave you at risk of rounding the bolt head, and removing the skin from a knuckle.
