Replacing limit screw on R8050 Di2 front derailleur
Any M4x8mm screw will work. I prefer using an allen head in these cases. The head on an allen head is less likely to be stripped than a phillips head. Apply some Anti-Seize or grease to the threads to help eliminate corrosion. The screw should be available at a local hardware or big box home improvement center. Your local hardwarestore will likely sell you a single screw. These are small screws so get two &quot;one to use and one to lose&quot;, just in case you drop it.
