What is the Difference Between a Keensert and a Helical Insert?Posted: March 16, 2021 Filed under: helical wire inserts, key-locking inserts | Tags: heli-coil, helicals, Keenserts, Key Locking Inserts, Wire inserts Leave a comment
What is a Helical Inset?
A Helical wire insert is a spring-like precision form wire coil that provides a permanent thread that’s stronger than the parent material. They are also often called a screw thread insert or a Helical insert, but the popular brand name is Heli-Coil, a registered trademark of Emhart Teknologies.
What is a KeyLocking Insert?
A key-locking insert is a solid bushing style insert that is threaded on the inside and the outside with keys on the top. It’s commonly called a Keensert or Keysert, and these are the registered trademark names of Huck Patents and Alcoa Fastening Systems.
Why Would I Use a Helical Insert vs. a Keensert, and Vice Versa?
- Strength: A key-locking insert is much stronger than a helical insert, particularly in high temperature and high torque environments.
- Ease of Install: A key-locking insert is easier to install than a helical wire insert.
- Price: A wire insert is much less expensive than a key-locking insert.
When Would I Use a Keensert?
In a heavy-ware, high vibration, high heat situation when you don’t need to save space and the whole depth is not a key consideration. The key-locking insert is the way to go.
When Would I Use a Helical Insert?
If you need to reduce costs, you’re minimizing space. The Helical wire insert is the way to go. They’re very useful for creating a permanent, strong thread and softer material like aluminum or titanium. And they’re best suited to the lower heat environments.
