The Exhaust Manifold 12 Point Locknut works by threading onto the bolts of the exhaust manifold. The 12-point design allows for a more accurate and evenly distributed application of torque during tightening. This ensures a reliable and stable connection, preventing leaks and providing optimal performance in high-temperature exhaust systems. This locknut contributes to the overall efficiency and proper functioning of the exhaust system in internal combustion engines.Attributes:• Withstands high Temperature of 870° Celsius.• Designed from heat-resistant and corrosion-resistant materials.• Facilitates a more secure and evenly distributed tightening.Applications: The Exhaust Manifold 12 Point Locknut securely fastens the exhaust manifold to the engine block, ensuring a tight and reliable seal. Its twelve-point design enhances torque application, providing stability in high-temperature exhaust conditions and preventing leaks.
