Good ideas, but features are spread too thin and there are some bugs and factual errors. For instance, tightening torque range for T25 is given as 15.9 to 19 Nm which is way too high for this size. Another bug: FG/fg tolerances for nominal diameter above 10 mm are shown as +0/-0 without warning.
Great handy tool for engineers. Need some improvements in visibility. Sometimes entered data is half cut
very useful app from mechanic to manager and technician to technical director . must have app.thanks Mechtab to give such a useful app for free of cost.
Very useful. All you need and not too much. Best app for toolmaker I could find.
as a design engineer, its a very handy app for anyone, still learning or well experienced
Amazing.... you have done a proper job..... thank you so much for this wonderful app which actually helped me..... i will never delete this app.
Good info still don't like the fact it's metric only not big deal simple conversion just saying
Very useful, Excellent. Try to include Gear calculations
I just love it , without doing lots of calculation just find out the value in a sec 👍
it is very good app for engineering work useful information is getting immediately thanks to providing that types app
this app is very useful and makes things easier.
Good for quickly searching the tolerances
very useful for quality design
Easy to use and very useful.
Excellent App for the workshop.
Good application to check thread measurements, machining speeds and basic bolt torques.
Most useful one for mechanical engineers
Very knowlwgable Tool in Automobile Field
Good app for precision reff...
Thank you for developping this application.
it helps me a lot thanks to mechanical tab.
Excellent app, 5 stars!!!
overall very usefull
So nice it's give more details I'll excited about this app
Useless for me. Only metric.
yes..., it's good.
Best handy info
Useful to engineers
all you need is here
Brilliant app that really is useful for almost evreyone. The solutions to a triangle I have found particularly good, it's saved me masses of time working out long-hand and is even quicker than using a caluclator. Hole and shaft tolerances is up to date and much quicker than havinng to troll through long lists of tolerances on paper. There are many other features that work equally as well as the ones I've metioned, to my mind you can't lose with this app.
