These bolts, well, they hold everything together. Specifically, they secure the flywheel to the crankshaft. They’re simple fasteners, but they’re designed to withstand a lot of stress – the force from the engine spinning, things like that. They’re typically high – grade steel, meaning they’re pretty tough. You’ll often see a specific grade marking on the bolt head itself, letting you know just how strong it is. Think of the flywheel as the engine's momentum keeper. The crankshaft spins, and that energy gets transferred into the flywheel to keep things going smoothly. These hex bolts are critical in making that connection secure. Without them, you won’t have a reliable transfer of power, and things will shake and vibrate badly. They’re right there in the heart of the engine, so they’re subject to a lot of heat and vibration. A loose or broken hex bolt in this area is a big deal. It’s not something you want to ignore. You’ll notice if one is failing – usually through a really rough idle, unusual noises, or even the engine stalling. If it breaks completely, you could end up with serious engine damage, so keeping these in good shape is really important for reliability. You can find replacements pretty easily; places like Fixparts Online have a good selection, and getting the right grade bolt is key. Don't just grab anything off the shelf. It’s a small part, but a vital one. Shop with confidence: Hex Bolt (MPN N90501402) comes with a 12-month warranty!
