Thanks guys for the suggestions and thank you terrywerm for your steps on how to work 316 stainless steel.I am checking into the OSG brand which I did contact them and told them that I wanted taps for a blind hole to make acorn nuts.OSG suggested this http://www.osgtool.com/7-16-14H53FXSEMI-BOTTEXOVA3TICN-p1723208.htm which is 40.00 that is more than my whole set of house brand taps but if this works for me then its a done deal.McMaster-Carr also has some that is also along bout the same price range,so I guess one is just as good as the other but I like OSG website which has lots of info.Please keep the thoughs coming,suggestions-----kroll
