🔧 Functionality of Tension Springs:

Also known as strain springs, tension springs work by storing mechanical energy when extended. When an external pulling force is applied, the spring stretches and generates a resistive force that attempts to pull the attached parts back together. Their tightly wound coils are specifically designed to resist this extension and return to their original form.

 

🧰 Hook and End Types:

We offer a variety of hook configurations for application-specific needs:

• Double Twisted Full Loop Over Center
• Long Round End Hook Over Center
• Hand Loop and Hook at Right Angles
• Machine Loop and Machine Hook

 

🧪 Materials Available:
