Guys I purchase alittle 316 SS hexagon bar stock to make afew oversize nuts in sizes 1/4-7/16.In the past I have drill and tap some SS but they were not perfect.One of the reasons that I later found out is as example 3/8 ,I had drill out a 5/16 hole for the 3/8 bolt size.I was told by someone that I could have went bigger than 5/16 still have good holding threads.Wish I could find that chart,since my computer went down I have nothing.
Anyway,I have the house brand set of taps and was wondering if there are taps made to handle stainless steel that don't cost arm/leg?
Does anyone have a drill chart that shows the % of threads,I don't remember what its called.Guys thanks again for any help forgive the lack of information ---kroll
