Extension spring with mixed hooks/Tension Springs

  Mixed hook extension springs refer to extension springs that combine two or more types of hooks on a single spring.These hooks can differ in shape, size, or even material. This design offers high flexibility and can meet various complex application requirements.


  Mixed hook extension springs are highly customizable spring products.Their flexible design and versatile functions make them widely applicable across many industries. If you need a spring that meets complex application requirements, mixed hook extension springs are an excellent choice.

Common Hook Combinations for Mixed Hook Extension Springs

  1. German hook + English hook: Combines the strong grip of the German hook with the versatility of the English hook.

  2. Short hook + Long hook: Meets installation needs with different space constraints.

  3. Round hook + Square hook: Adapts to different shapes of mounting holes.

  4. Special-shaped hooks: Custom hooks designed according to customer requirements.

Extension Springs/V-shaped hooks
  V-shaped German hook extension springs refer to extension springs with hooks at both ends designed in a V shape, originating from Germany, hence called German hooks.Compared to traditional round hooks, the V-shaped hooks provide stronger grip, making the spring less likely to detach under load.  V-shaped German hook extension springs feature a specialized hook shape suitable for unique assemblies where tensile force is applied. When stretched, the spring exerts a counteracting force using its restoring tension.

Extension Springs/Side Hooks
  Side-hook extension springs refer to springs with hooks designed on the edge rather than at the spring’s mean diameter.This design allows the hooks to achieve more precise positioning during extension and provides more stable tension when under load.  Side-hook extension springs are suitable for applications where the hooks engage on flat or planar surfaces. Like other extension springs, they operate by exerting a counteracting force using the restoring tension when stretched.

Extension Springs/Side Hooks

Extension Spring/English Hook
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.

Short German Hook Tension Springs/Extension Springs
 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.

Extension Spring/Small Outer Diameter Hooks
  Small outer diameter extension springs are mostly customized products requested by customers. They are helical springs that elastically deform under axial tensile force. Unlike compression springs, extension springs typically have coils that are tightly wound without external force applied, requiring a certain amount of tension to separate the coils.  These extension springs feature a small outer diameter with hooks at both ends. Due to their small outer diameter, they can provide strong tension even in limited space, making them widely used in precision instruments, electronic products, and other fields.
