A Hex Nut creates a firm and stable connection, ensuring proper electrical conductivity. This connection allows the tachometer-sending unit to accurately measure the engine speed and transmit the corresponding revolution per minute (RPM) signal to the tachometer. It is made from aluminum material for its strength, conductivity, and durabilityAttributes:• Preventing loosening or disconnection during operation• Provides excellent electrical conductivityApplications:A Hex Nut secures and provides an electrical connection between the tachometer sending unit, allowing for accurate measurement of engine speed. The internal threads provide a proper fit and electrical connection.
