English Hook Tension Springs

  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.

  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 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.

  Swivel hook extension springs are a highly versatile type of extension spring.Unlike standard hooks, the hooks on both ends of a swivel hook extension spring are designed to freely rotate, which greatly enhances the spring’s flexibility and allows it to perform exceptionally well in various specialized equipment.  They are primarily used in mechanical devices, and the main difference from regular hooks is that both ends can rotate, providing added adaptability. Therefore, swivel hook extension springs are considered a highly practical spring type, widely used across many fields due to their flexible nature.  When selecting a swivel hook extension spring, it is important to consider the specific application requirements, taking into account factors such as hook type, material, and dimensions. These factors are often critical and make swivel hook extension springs the preferred choice for many customers.  Swivel hook extension springs are a very practical type of spring, and their flexible characteristics enable them to be widely used in numerous industries. When choosing a swivel hook extension spring, it is essential to comprehensively evaluate the hook design, materials, and dimensions according to the specific application needs.
