If the Bolt is overtightened, it can be damaged. We recommend tightening to a max of 2.5Nm. The best way to approximate this without a torque wrench is to use a small hex key oriented lengthwise inline with the Bolt. Then tighten firmly.
Note: Our Bolt is paired with a rubber Grommet for proper isolation of the Dome and full resonance. Transfer your existing Grommet or purchase replacement rubber parts to be used with any new Bolt.
