First M15 Octalink Crank Bolt (2397) is a crank-arm fixing bolt designed to secure a compatible crank arm firmly to an Octalink-type bottom-bracket spindle.
Main Features
Construction and Design
The bolt is made from durable metal and designed to withstand the loads generated within the crank assembly. Its M15 thread provides a secure connection with a compatible bottom-bracket spindle.
Key Functions
The bolt pulls the crank arm onto the spindle and helps maintain stable drivetrain operation. Correct tightening reduces the risk of crank movement, loosening and damage to the interface.

Additional Features
The bolt should be installed using the correct tool and tightened to the torque specified by the crank manufacturer. A worn, damaged or deformed bolt should be replaced to ensure secure crank-arm attachment.
Summary
The First M15 bolt is intended for installing and repairing Octalink cranksets. It is suitable for bicycle mechanics and riders who require a replacement crank fixing bolt with an M15 thread.
