31306779823 BMW COLLAR SCREW

This little guy basically holds things in place and keeps them aligned. Think of it as a precisely engineered pin, but with a threaded section so it can be securely tightened. It’s designed to resist rotational movement and keep parts from drifting or vibrating loose. It transmits force, but isn’t really meant to be the load – bearing component – more like a strong connector. You’ll typically find these used on axles and shafts, frequently in the drivetrain. It might hold a hub onto a shaft, secure a component to a splined section, or keep a bearing assembly from shifting. Specific location varies depending on the vehicle, but generally it’s a critical piece supporting rotational power transfer. Sometimes you'll see them used in steering components too, keeping things stable. If a collar screw fails or works loose, you’ll notice if you’re lucky. It usually starts as a vibration, a clunking sound when you turn or accelerate, or unusual wear on nearby parts. If it completely fails, things can get seriously unstable. That assembly will start to move around, damaging other components, and ultimately leading to a breakdown. It's a small part, but a really important safety and functionality item. You can find these pretty readily, and places like Fixparts Online usually have a good selection. Replacing a worn or damaged collar screw is a relatively simple fix that can prevent a lot of bigger problems down the road.
