I guess this is the right newsgroup for this one. Its not quite Sieg v Myford but you can't get more than meccano.....My 7 yr old has one of the (French manufactured) meccano sets. Alas, he is having difficulty because the nuts and bolts keep coming undone - and its turning him off it.I don't seem to remember having that much trouble 45 yrs ago when i used to be an avid fan. Its not just him - even when i tighten them, they will still work loose with ordinary handling.The bolts are different from those I remember - these are allen headed black things (diameter outside thread 3.5mm - sorry haven't got a thread gauge). The nuts look similar to my youth - square not hexagonal but i remember them as marginally thicker. There are many more bolt length options than I ever used to have as well.There are some nyloc nuts in the set and I have also locknutted the critical ones and tried the old varnish trick on the thread but none of these are a sensible solution. I did ask the chap with all the Army Meccano models at Brighton exhibition earlier this year but he didn't have the problem.I guess the nuts or bolts are cheapo with too much clearance and I would be perfectly happy to buy him some good ones if it means he xxx we can get on with the big crane with motor - but what do I get and where from - and would normal hexagonal nuts be Ok for 7 yr old fingers?Ken

Yes, I think we both have to admit defeat and bow down in admiration to a true grand master in sad bastardy.

I do remember the sound of the ones that dropped off my clockwork motor powered Meccano rug crawler when they hit the fan in mum's hoover. And those tiny fish-plates jamming the belt drive to the beats as it cleans rotating brush thingy.
