Park Tool TAP-8 Frame Tap

The TAP-8 is a 5 x 0.8mm frame tap specifically intended for cleaning out or chasing damaged threads on bicycle frames. It is ideal for removing debris, paint, or minor burrs from existing threaded holes to ensure bolts install smoothly.

No, this is a thread-chasing tool, not a cutting tap. It is designed to restore and clean existing threads, not to create new ones in unthreaded material.

This tap is sized at 5 x 0.8mm, which is the standard thread pitch for most M5 water bottle cage bolts and derailleur hanger mounting points. Always verify the thread pitch of the specific hole you are working on before attempting to use the tap.

Yes, you will need a tap handle or a small adjustable wrench to turn the tool. Ensure you keep the tap perfectly aligned with the hole while turning to avoid cross-threading or damaging the frame.

While it is a precision tool, you should always use a light touch and plenty of cutting fluid or lubricant. If you feel significant resistance, stop immediately, back the tap out, and clear any debris, as forcing it can strip the threads further.
