This is a basic calculator for the ISO screw connections, which allows you to calculate all the most important parameters of the connection, with the possibility of calculating these parameters for the different types of screws and for the different types of connection.

The basic calculator is a very simple and easy-to-use tool, which can be used by everyone, even if they have no knowledge of any technical language.

In order to use the basic calculator, you need to enter the following information:

• The material ultimate stress.
• The material yield stress.
• The material maximum compression stress.
• The bolt head – plate friction coefficient.
• The external axial load.
• The torque.
• The length of the screws.
• The hole depth.
• The nominal and actual diameters of the screws.
• The length of the connection.
