FSA Crank Bolt

The integrated cap allows you to remove your crank arm using only a hex wrench. As you unscrew the main bolt, the cap pushes against the crank arm, effectively pulling it off the spindle without needing a separate crank puller tool.

This bolt is specifically designed for crank systems that require an M18 bolt and an M30 cap configuration. It is primarily intended for BMX applications, so please verify your current crankset's thread size before purchasing.

Yes, this is a complete assembly. It includes the M18 crank bolt and the integrated M30 self-extracting cap as a single unit.

It is good practice to apply a light layer of bicycle-specific grease to the threads before installation. This prevents the bolt from seizing over time and ensures you can easily remove it during future maintenance.

This specific part is engineered for BMX crank systems. While some thread sizes may overlap, you should only use this if your crankset specifically calls for an M18/M30 configuration to ensure a safe and secure fit.
