Gentlemen (and Ladies of course)
I have a male threaded component with what seems to be a 3/16" x 28tpi thread using my UNF pitch gauge and digital caliper.
When I originally tried the identication, I only had the female part and thought it was 5mm x 0.8 pitch then 10-32 UNF, but I was wrong.
Having just surfed this looks like a UNS thread. That is 10-28 UNS with a diameter of 0.1890". This is a series I have never heard of until now.
Can anyone confirm this theory? It belongs to a stainless steel clamp designed to hold PTFE ball joints together in air emissions testing equipment.
Where would I get a spiral pointed machine tap from in UK? I can't see one on J&L.
Thanks in anticipation
