So many have asked me now where I buy the brass hardware and this lead me to make this little call out!
I have found no supplier in Denmark where I come from.
Since my GF is French I come every four weeks to Paris and there I found that the BHV Grand Magasin have a nice selection to buy from in their tool and hardware department in the basement.
In US I just made this search on E-bay: (knurled brass nut)
Or: (knurled brass)
Or: (Thumb screw brass)
In UK I did not find any, but you can order from the French web shop, then there are no extra costs like from US.
I think it could be wonderful if you put links here if you can help in any country:
