• Hooks ຂ້າງ: The hook extends directly from the side of the spring without crossing the center. This is used when a specific alignment is needed.

Why Do Hooks Break at the Bend?

The main body of your spring is perfectly intact, yet the hook has snapped clean off. This seems like a design flaw, but why does it happen so consistently at that one spot?

The hook breaks at the bend because this is a point of extreme stress concentration. While the load is distributed across all the coils in the spring's body, the entire force is focused on that one small, bent section of wire.

I like to use the simple analogy of a paperclip. If you want to break a paperclip, you don't just pull on it—you bend a small section back and forth. The metal fatigues and breaks quickly. The same thing happens to a spring hook. Every time the spring is stretched and released, that bend is subjected to intense stress. For a simple crossover hook, the bend is quite sharp, making the stress even worse. This is why we pay so much attention to the radius of that bend. A larger, more gradual radius helps to distribute the stress over a wider area, dramatically increasing the hook's fatigue life and preventing it from failing.

The Science of the Weakest Point

Understanding stress is key to preventing failure.

• ຄວາມເຂັ້ມຂຸ້ນຂອງຄວາມກົດດັນ: Any sharp corner or bend in a metal part creates a point where stress can build up. Under repeated loading, this is where a crack will start.
• Fatigue Failure: Most hook failures are not because the load was too heavy once, but because a smaller load was applied thousands of times, causing the metal to fatigue and break.

How Can You Customize a Hook for Your Application?

A standard hook doesn't fit your product's design. It's either too long, too short, or the opening is the wrong size, forcing you to compromise on your design.

Extension spring hooks are highly customizable. You can specify the length of the hook, the size of the opening (ຊ່ອງຫວ່າງ), and even the orientation of the hooks relative to each other to ensure a perfect fit for your assembly.

This is where working with a custom spring manufacturer really pays off. A client once came to us with a problem: their assembly process was slow because workers had to manually twist each spring to align the hooks. We solved this by manufacturing the springs with the hooks oriented at a 90-degree angle to each other, so they would drop into place perfectly every time. We can also create extended hooks to reach a distant anchor point or create a special V-hook to sit securely in a groove. The hook doesn't have to be a standard part; it can be an integral, custom-designed component of your product.

Tailoring the Ends to Fit Perfectly

Customization solves assembly and performance problems.

• Hook ຄວາມຍາວ: Hooks can be made with extended ends to eliminate the need for extra connecting hardware.
• Gap Opening: The size of the opening at the tip of the hook can be precisely controlled to ensure a secure connection.
• Hook Orientation: The angle between the hook on one end and the hook on the other can be set to 0, 90, 180, or any other angle required for your assembly.

The hooks are the most vital part of an extension spring. Choosing the right type, understanding why they fail, and customizing them for your specific needs are essential for product reliability[^ 1].
