Quantity: sold as a standard set of 8 pieces. Anti-seize properties: steel nuts frequently rust-weld themselves to cylinder head studs due the extreme heat cycles of an air-cooled engine. Because brass expands and contracts predictably does not rust, these nuts resist seizing. Material: high-quality solid brass.

Hex head size: 11mm wrench size standard m8 nuts typically require a larger 13mm. They can be safely removed during future top-end maintenance without snapping the studs. Why engine builders use them standard 13mm hex nuts present a severe fitment bottleneck when upgrading to larger 1-1/2 or 1-5/8 aftermarket performance exhaust headers dual-carburetor intake manifolds.
