FAQs
What size is this Shimano clamp bolt?
This is an M5 x 13.5 mm clamp bolt.
Does this bolt come with a washer?
Yes, this clamp bolt includes a washer.
What front derailleur model is this bolt for?
It is designed for the Shimano FD-6600 front derailleur.
Can I use this bolt on other brands of front derailleurs?
While it might physically fit derailleurs with an M5 thread, it is specifically designed and recommended for Shimano FD-6600 for optimal performance and compatibility.
How tight should I make the clamp bolt?
Always refer to Shimano's official service instructions for the recommended torque specification. Generally, it should be snug and secure without overtightening.
What happens if I overtighten the bolt?
Overtightening can strip the threads on the bolt or the frame mount, potentially requiring costly repairs.
Where can I find the torque specification?
Torque specifications are usually found in the technical documents or service manuals provided by Shimano for the specific derailleur model, often available on their website.
Troubleshooting
Bolt will not thread into the frame mount.
Ensure you are using the correct bolt (M5) and that the frame's thread is clean and undamaged. If the frame threads are damaged, professional repair may be needed.
Front derailleur is loose after tightening the bolt.
Verify the washer is present and correctly seated. Ensure you are tightening the bolt to the recommended torque specification; overtightening can strip threads, while undertightening leads to looseness.
Difficulty achieving proper front derailleur alignment.
Confirm the bolt size and length are correct for your derailleur clamp. Ensure the derailleur is positioned at the correct height and angle before fully tightening the bolt.

Setup, Compatibility & Care
Setup: To install, first remove the old clamp bolt. Position the front derailleur at the correct height and angle relative to the chainrings. Insert the new M5 x 13.5 mm clamp bolt with its washer through the derailleur's clamp mechanism and into the frame mount. Tighten the bolt gradually and evenly to the manufacturer's recommended torque specification. Ensure the derailleur cage is parallel to the chainrings.
Compatibility: This clamp bolt is specifically designed for the Shimano FD-6600 front derailleur. While it may fit other clamp-on front derailleurs with the same M5 thread size, it is best used with its intended component for guaranteed performance and fit.
Care: Keep the bolt and threads clean from dirt and grime. Periodically check that the clamp bolt remains tight. If removed for maintenance, reapply a small amount of light grease to the threads before reinstallation to prevent seizing.
