I've got dozens of old ones if an 8mm thread would do you. They're flanged ones like these. http://www.philidasfasteners.co.uk/prod_flange.htm I could nip the flanges off on the lathe if that would help but you could just weld round the flange anyway. -- Dave Baker

I've found them on stuff but never bought any. So, do they actually 'lock' in use or would they allow something like said eyebolt to be removed by hand would you think please? I was looking for some resistance to stop them undoing if in the trailer and unused but to be removable by hand if they were in the way. Cheers, T i m

Thanks very much for the offer Dave but these are 10mm x summat. > They're flanged ones like these. > >http://www.philidasfasteners.co.uk/prod_flange.htm Ah, ok. So they would provide resistance that could be overcome by hand on a 40mm diameter eyebolt ring would you think please? > >I could nip the flanges off on the lathe if that would help but you could >just weld round the flange anyway. Indeed (but thanks again). Cheers, T i m
