Re: Stripped mounting stud socket
The tap usually has the drill size needed on it or the instructions tell you what size drill bit to use. When taping a hole you have to go slow turning the tap in a little then backing it out then turn in a little deeper. This method cleans out the shaving created while cutting the threads. Use plenty of oil, I sometime stop about half way and wash out the hole with wd40 then blow it out with air then reoil and thread it till its deep enough. You can see this on you tube if you want.
Your results may not be the same,Greg
