The nominal size given in your link is the B.S.I. recommended which is also in the Zeus tables.
I've told you. 1/4 BSF, or just use M6 and don't overtighten them. Easy. Christ, if you were in Leeds I would have come round and done it for you!Sh*t - you guys are doing my head in...I just need some fecking bolts to hold me stands together

It would. That's why I didn't say it. Nice strawman though.How do you work that one out?
In a workshop with imperial, metric, number and letter drills, it just happend to be the number drills that were a best fit to BA tapping drill requirements.
What you are effectively saying is that there are no drills at tapping sizes for BA threads, just lucky happenstance that number drills do the job. That would be insane.
I have a photocopy of the "Ocker Bolts" catalogue offering the same thing. My dad used to be a craft teacher, he had a copy on the school workshop wall. One day a lad came to him with a rather abused bit of metal and said "I think I need one of those bolts there on that poster, have you got one?" He was apparently rather crestfallen when my dad explained that he needed to fix the problem with more conventional engineering methods, such as drilling the hole straight, the right size and in the right position to start with.Oh, good: I was just going to add to all the help above, this being 'DIY" - now - what fastener style of M6 is it you require..?
