Coiled spring pins

Have you ever played with a slinky? It's a long, thin, metal toy that can stretch and bounce back into a coil. Well, coiled spring pins are similar, but much smaller and made of stronger metal.

Picture a tiny, thin piece of metal that's been wound into a tight coil like a spring. When it's inserted into a hole, the coil is compressed and springs back, holding the metal together.

Coiled spring pins are used in machinery, engines, and even in some toys. They can be very strong and durable, and they're often used to hold different parts of machines and equipment together.

So, just like a slinky, but smaller and stronger, coiled spring pins are a useful tool for keeping things together.
