Hi Gpavlab, Thanks for taking the time to reply to my question. I think you you misunderstood my question i am broaching 4mm hex holes and wanted to know the tolerance across the flats of the hex hole. I managed to get the information from a photo copy of BSI handbook 44. Just so you can sleep...
Hi I am new to this site and was wondering if any body knew the tolerance for a 4mm a/f hex broached hole. The drawing just asks for 4.07 a/f but no tolerance, I know the information is available in the machinist/engineers hand book but I do not presently own a copy, any help on this question...
