Fantastic app – iEngineer Review

I have been using this app practically since it was first released. It is the best app for getting all the info you need about bolts and screws - including metric ones. The clean interface has been made even better with the iOS 11 update. It is no a machinist bible and does not pretend to be one. If you just need info on a bolt, what through hole or tap hole to drill, fraction to decimal conversions, etc. this is the best you'll find.
