These bolts basically just clamp things together. They have a six – sided head – that’s the “hex” part – and a threaded shaft. You tighten them with a wrench, and that tightening force holds whatever they’re connecting securely. They come in different sizes and strengths, naturally. When you see these listed under ‘Exhaust Hardware’, that’s exactly where they’re used. They hold all the pieces of your exhaust system together – the pipes, the muffler, the catalytic converter, the heat shields… everything. You’ll find them anywhere there’s a flange connection, or where you need to attach a bracket. They’re used throughout the entire vehicle really, but this listing is specifically for exhaust applications. Well, your exhaust system has to be completely sealed to avoid leaks. Exhaust gases are nasty – they’re hot, smelly, and can even be dangerous if they get inside the cabin. These bolts act like a shield, keeping everything tightly connected and preventing those leaks. If one goes missing, or gets corroded and breaks, you’ll notice it pretty quickly – you’ll hear a hissing or rattling sound, and possibly smell exhaust fumes. Even a small leak can cause performance issues and, eventually, could lead to bigger problems. You can find a huge selection of sizes and grades at places like Fixparts Online – it's always best to match the original bolt exactly, both in size and strength, for a proper, safe repair.
