When changing a cylinder kit or an exhaust, it's a good idea to pick up a few extra 8mm Studs, since these can easily need replacing and bring your project to a grinding halt while you wait.
These nuts are essential. The smaller, 10mm diameter head allows for extra clearance between your wrench and the head for easy access.
Standard 8mm thread diameter.
