Extension Spring/Small Outer Diameter Hooks

Extension springs are designed to resist pulling forces and return to their original length when the load is released.The English hook type features a loop that is concentric with the spring body, offering balanced stress distribution and a neat, symmetrical appearance.Features:Concentric loop provides even load distribution.Simple structure and easy installation.Suitable for general industrial, mechanical, and household applications.Available with various surface finishes such as zinc plated, color zinc plated, or stainless steel.

  Long German hook extension springs are a common type of extension spring featuring long German-style triangular hooks at both ends.This design increases the contact area between the hooks and the fixture under load, enhancing grip and thereby improving the spring’s reliability.  Long German hook extension springs are mostly used in electronic and electrical products. Like other extension springs, they operate by exerting a counteracting force when stretched, utilizing the restoring tension force.

 Short German hook extension springs are a specialized type of extension spring featuring short German-style triangular hooks at both ends.This design enables the spring to provide strong tension within limited space and allows for a more compact installation. The short German hook is compact and robust, making it suitable for applications with restricted space and customizable development according to customer requirements.  The short German hook is ideal when the hook area on the product is small. Like other extension springs, it works by exerting a counteracting force when stretched, utilizing the restoring tension force. 

  German hook extension springs are a common type of spring characterized by German hooks at both ends.The German hook is typically triangular or V-shaped, offering a larger contact area and stronger gripping force, which allows for secure connections with other components.  With their unique hook design and excellent performance, German hook extension springs are widely used across various industries. Understanding the features and applications of German hook extension springs is essential for effectively selecting and using extension springs.  The working principle of an extension spring is to generate a counteracting force when stretched or pulled apart. By utilizing the restoring force (tension) after being extended, these springs can control the movement of mechanical parts, absorb and store energy, and measure force.
