Key Locking Inserts

How to choose the length of a key locking insert?

Materials like steel do not require long inserts, whereas applications with soft materials like aluminium might need a longer insert.

What is the difference between key locking inserts and thread locking inserts?

What are the advantages of a key locking insert over a helical threaded insert?

Helical threaded inserts usually have a tang or piece of material that acts as a catch point for the installation tool. When the tang is broken off during installation, it can end up loose inside the application and cause short-circuiting or other malfunctions. There is no such danger with key locking inserts, making them a safer solution.
