TOOPRE TL-S27 FSA Crank Cap Tool – 45# Steel 6-Pin Socket for M27 Self-Extracting Crank Arm Bolt Installation & Removal

The right tool for FSA crank maintenance.

The TOOPRE TL-S27 is a purpose-built socket tool designed for installing and removing the M27 self-extracting crank arm caps found on FSA cranksets. Machined from hardened 45# high carbon steel with a precision 6-pin engagement face, it locks into the crank cap securely — no slipping, no rounding, no damaged components. Whether you're swapping crank arms, servicing bearings, or rebuilding your bottom bracket, this tool makes the job clean and effortless.

Key Features

• Hardened 45# High Carbon Steel — Quenched and heat-treated for superior hardness and torque resistance. Electroplated finish provides long-lasting rust and corrosion protection.
• Precision 6-Pin Engagement — Six accurately machined steel pins mesh perfectly with the FSA M27 crank cap holes, distributing torque evenly and preventing cam-out or stripping.
• CNC-Machined Accuracy — Full CNC integrated machining ensures the pin positions and tooth profile align precisely with the crank screw cap every time.
• Chamfered & Deburred Edges — All contact edges are lead-angle treated for a smooth, burr-free finish that won't scratch or damage your crank arm surface.
• 19mm Hex Drive — The top hex accepts a standard 19mm open-end wrench or adjustable wrench, giving you solid leverage for tightening and loosening.
• Compact & Portable — At just 72g and under 35mm tall, it fits easily in any tool roll or workshop drawer.

How to Use

1. Align the six pins on the tool with the corresponding holes on the FSA crank cap.
2. Fit a 19mm open-end wrench (or adjustable wrench) onto the hex body.
3. Turn counterclockwise to remove, or clockwise to install and tighten to the manufacturer's specified torque (typically 38.4 Nm for FSA M27 caps).
