Re: i need help
If the nuts are plated then you will struggle to get any adhesive to bond to them properly. Using un-plated nuts (look for 'black' or 'self colour' in their product description. will certainly make life much easier.
They will also need to be thoroughly cleaned and, ideally, have the surface roughened with an abrasive. Having them sand blasted should achieve both. Once they are cleaned, make sure they stay clean, eg don't handle them with bare hands.
For this kind of thing using an adhesive is very much a second best option compared to welding or brazing.
