Indeed. The tap I'd borrowed was softer than the nut. It has now been cleaned out properly, and an M10 does fit, if somewhat still a bit tightly. Thanks for the tip, but not for assuming I am a complete fool.

I have had an issue with a set of threads on a rear crossmember that proved tricky. Admittedly this sounds very simple. The bolt that sheared did so when undoing it, so wasn't a case of brute force and ignorance. I have had vehicles for 35 years, and done a fair bit of work on them over the years, usually without issues, including fitting towbars.
Someone else did do this. A professional mechanic. he did say it was still a bit tight. Thanks for your enlightenment though. Just for the record, I may have had a few issues with a seemingly very simple task, but in my defence, I have undertaken 'safety critical' work on many vehicles over 35 years, but will stop now, as I've obviously not any idea what I am doing.

Another thing to bear in mind is that the nuts would have shrunk slightly when they cool after being welded, and that in itself could be the resaon for the tight bolt which sheared!!
Not that I'm a mechanic or anything ...

A really useful thread to find. I'm having the same problem having replaced the rear cross members. In my case I'm sure its the heavy galvanising that's choking the nuts. Needed to know what bolts should really fit. Thanks
Galvanising inevitably clogs up the threads. You'll need to run some M10 taps through.

better get someone else to look at it
Something else to bear in mind that a proper tap set will have 3 of each size. A taper tap for starting and a plug tap for threading to the bottom won't be included if you get a basic set. If the holes areblind then you will need a plug tap to clean out all the way but you may struggle to get one started straight if the threads are well galved up
I am fairly handy with the tools but rubbish with a tap and die...
don' t own any tap n die, get the farmer or his son to do mine as they are dab hands at it while i make the tea...
which i very well qualified for... ( 11 years working for British Rail back in the day...)
Same as hate doing timing belts.. get a mate or the farmers son to do them i strip to a point leave the critical bit to them then reassemble.. have done one or two but not a great fan and always struggle.. better at making the wets..lol
