Seems to work great but missing a common bolt. No option for flange head bolts which are very common in automotive and power sports. For example a M12 hex bolt uses a 19mm wrench but an M12 flange head on your car may use an 18mm wrench. Be great if these were shown in the app. All SAE I've seen use same wrench size for standard hex and flange head hex.

Love the app, but long over due for an update. Especially as its the paid version. Would really like to see larger sizes added like M30 3.5 thread etc.

Thanks for the feedback. I'll look into adding larger sizes. I also just did an update so it looks a bit better and gets rid of the warning about being compiled for an old version of android.

No information about matching Nuts. App description does not mention nuts So change the name. See app called Fasteners for example. I use this info daily in my Shop
