Small Imperial sizes missing
Needed dimensions of UNF 10-32 (3/16”) but app’s smallest SAE size is 1/4”.
Excellent go-to app for thread data
This is the app I reach for when designing and cutting screw threads. It cover a wide range of standard metric coarse, fine and non-standard combinations. On the odd occasion I make Unified threads this app has been good for these too. Has replaced Zeus etc. tables for me.
Great App
Amazing app to use.
No better place to check the size of the bolts to fit my nuts.
There’s nowhere else I’d go for a good quality screw

Updated review after update
Thanks Hague. Works a treat, good to have the app working on my phone again.
Great Update
Works so much better since update, great for thread calculations.
