Excellent App
Excellent app. I use it daily on the Shop Floor. The $1.99 upgrade for the metric information is well worth it.
If you work in Maintenance or the Machine Shop I highly recommend it. It’s a lot easier than digging that reference book out of your toolbox or going to the chart on the wall.

Works as advertised
I use it a lot to see if things are in a ball park of right torque. Pretty helpful with automotive stuff too. A lot of people are complaining that the app doesn’t have a lot of extra functions but it works as advertised.
It is worth it, every penny
I use this app almost everyday at work. It has been the perfect reference for countless confusing situations. If you do FEA or CAD, you NEED this app.
Great App for a hobbyist
I’m a hobbyist who machines and fabricates for my own projects. This app is very handy for me. It saves me from looking up screw dimensions in handbooks and walking to where I keep a drill chart. I do wish it had a tap drill table, that’d save me even more time. I read a review which mentioned tensile strength of some fasteners being different than other references. I haven’t compared those in the app to other references. I only use the dimensions and haven’t, so far, found any discrepancies. Good eye to the reviewer who caught those.

Great useful app with some small errors
The app is very useful and convenient to use. I would give it a 5 star review, if it wasn’t for a few errors that can be easily rectified.
For metric bolts of class 10.9 and 12.9 the proof strength is lower than what’s specified in the standards. Additionally, the calculation of the tensile stress area for all metric bolts is a bit off. Those two factors together leads the app to suggest a torque figure that’s lower than it should be. There’s an error in the tensile area calculation for SAE bolts too, but here it’s small enough to not really affect the suggested torque.

Useful app
Great pocket reference to have on hand in the workshop. Bought as a quick reference in the machine shop as books are far too expensive to use in that environment despite being laminated and this is less than a couple of quid! Extremely useful for threading reference for lathe and milling work.
A must for fabricators or maintenance techs!
Love this app! Quick and easy to use with all the information you need in one place. Great tech support also.
5 star
Wouldn’t be without it very useful to have to n your pocket.
Great app
Great reference, valuable information. Thank you.
Outstanding Resource - Long Time User
I have been using this app for many years. It has been an outstanding resource. My only complaint is there are no loose fit clearance hole sizes for US Screws. Tight and Normal fit are present for US Screws. I certainly will not remove a star for that minor complaint, since the remainder of the app is so great! Highly recommended.
