Brass Exhaust Manifold Nuts – High Temperature Hex Metric & UNF UNC Sizes M8 M10

Brass Exhaust Manifold Nuts – High Temperature Performance for Manifolds & Turbos

These high-quality brass exhaust manifold nuts are specifically designed for high-temperature environments such as exhaust manifolds, turbochargers, and inlet systems. The brass construction helps resist corrosion and reduces the risk of seizure on manifold studs, making installation and future removal easier — particularly in demanding heat-exposed applications.

Manufactured for durability and heat resistance, these nuts provide a reliable and secure fastening solution for automotive repairs, performance upgrades, and restoration projects.

Available in both metric and imperial thread sizes to suit a wide range of vehicles and engineering applications.
