Fastener Designer is our new web-based tool that allows you to calculate complex fastening connections in a simple way.

The tool provides a simple and easy-to-use interface, with a dynamic 3D viewer and integrated tutorials that help you get started.

The tool is free to use and does not require any login. Nevertheless, you can save your calculations to your device and continue your project later. You can also save your calculation as a template which helps you save time on future calculations.
