Posts for Tension Springs（Post Shape：Hex Socket）

Tension spring posts are spring posts used to fasten tension springs. They function as supports that fasten both ends of a tension spring to stabilize vibrations in it. Posts are available in the standard cylindrical type that attaches the tension spring to a hole in the post, and a hexagonal cylindrical type that attaches the spring to a groove. Various other types can also be selected to match different usage environments. Examples include models attached with a wrench, and roller models that prevent tension spring hooks from scratching. Posts are usually made of stainless steel with a black oxide coating surface treatment. A lineup of sizes is available to support various tension spring and screw sizes, so models should be selected to match the applicable size and usage objective.

FAQ Posts for Tension Springs

Question: What are tension spring posts used for?: Answer: Tension spring posts are essential components used to fasten tension springs. They serve as supports to secure both ends of a tension spring, stabilizing vibrations and ensuring efficient operation. Common applications include use in electronic appliances, automotive parts, robotics, and medical devices
Question: What types of tension spring posts are available?: Answer: There are several types of tension spring posts, including:
• Hole Type: These posts have holes where the tension springs can be hooked.
• Groove Type: These posts have grooves to secure the springs.
• Notched Type: These posts feature notches for easy hanging of tension springs.
• Hex Type: These can be attached using a wrench.
• Roller Type: These have rollers to prevent damage to the tension spring hooks.
Question: How do I choose the right tension spring post?: Answer: To choose the appropriate tension spring post, consider the following factors:
• Mounting Screw Size: Ensure the post matches the screw size of your application (e.g., M3, M4, M5, etc.).
