snap fit calculator - beta

A snap fit is a simple assembly method that joins two parts without using any additional components or fasteners.

This calculator provides a simple way to derive snap-in force, engagement force, and stress at root for snap fits. This is based on your inputs for material, dimensions, and loads.

For demonstrational purposes only. Feel free to let us know what enhancements you would like to see in this web app by providing us feedback.
