## What is Torque Calc?

Torque Calculator- this app is intended for plant and field estimation of a torque value based on bolt size or nut size and lubrication. Simply select bolt size and nut size and view torque values for specified lubricants. Now includes newton/metre conversion for all bolting requirements.

• Take the guess work out of Torquing. easily view recommended torque values with just one touch. 

• Find precision torque values based on bolt and nut size. 

• This calculator is a must for plant and field bolting of any critical bolting application. 

• Industry applications include Pipeline flanges, Pressure Vessels, BOP Stacks, Frac Stacks, Compressors, Heavy Equipment, Mining Equipment, Wind Turbines, Locomotives, Cranes and more. 

• When you can't do it by hand, Torque is critical.

### 1/5 — Poor range

*2019-11-12*

Has limited range of sizes starting at 22mm and up

### 1/5 — No good

*2018-07-23*

Only diameter. Doesn’t tell you if UNF/UNC or TPI 
Useless

### 1/5 — nothing that great

*2017-06-12, version 1.4.0*

Waste of my money that I paid. There are other apps for free that do more.

### 2/5 — look before you buy !!

*2015-01-11, version 1.1.0*

I can’t use this Torque Calc because the smallest stud size they have is 3/4” in diameter. It would be nice if they went down to 1/2” or so for your everyday mechanic.
Basically, it’s useless for me

### 3/5 — Useful For nut sizes but......

*2014-05-13, version 1.1.0*

Only thing I see this app being useful for is a quick reference for nut sizes and figure out a close approximation in Newton/Meters.   No adjustability in load values...

### 5/5 — Sales Representative

*2014-04-08, version 1.0.0*

Quick references like this one save tons of time in the field. This is a col app!

### 5/5 — Bolting Specialist

*2014-03-22, version 1.0.0*

This app is simple to use and very user friendly for bolting applications in the field.

### 5/5 — Torque Calc

*2014-03-22, version 1.0.0*

The Torque Calc app is a simple, clean, quick responding design, just what you would want a design to be.

### 5/5 — Great App

*2014-02-22, version 1.0.0*

Very simple & easy to use! Easier than reading a chart on paper! Very happy about this.
