036109651C Audi COTTER

Basically, a cotter pin is a simple fastening device. It’s a metal rod, usually split in two, that you slide through a hole to secure a castle nut. Think of it like a little plug that keeps the nut from backing off. It’s really just holding things together mechanically. You’ll find these all over, but a big place is on the front wheels, holding the axle nuts in place. They also show up in steering components, suspension, and even some engine parts. Any place where a nut needs to be absolutely secure, especially under vibration or stress, you’ll likely find a cotter pin. It works with a castellated nut—a nut with slots cut in it—so you can only tighten it to a certain point, and then the pin locks it in place. Honestly, these are a safety thing. If a castle nut comes loose—like on a wheel—you’ve got a serious problem. The cotter pin acts like a shield, preventing that from happening. It’s a fail – safe. They're inexpensive, and easy to replace, so it’s much better to deal with a simple cotter pin issue than a bigger, more dangerous one. You’ll notice if one is missing, typically during an inspection, because the nut will have some play. We stock a wide range of sizes, and you can often find what you need quickly at places like Fixparts Online. Just make sure you get the right size for the application, or it won't work correctly.
