This App is not a professional Software, but provide you a Basic Calculation for the ISO screw connections. Starting from the dimensions of the screws and the mechanical & physical properties of the connection, this App calculates simultaneously all the most important parameters usually considered for the stability of the Screw connection. A green light tells you if the value of the parameter is enough to ensure a minimum Safety Factor of 1.1, otherwise the value becomes red. As said the Software is not professional, therefore use this App just for a fast and preliminary check.
