Frame taps will become a lifesaver at some time for virtually every mechanic. The TAP-7 can be used to clean, chase, and restore M3 x 0.5 threads, commonly found on rear dropout alignment screws. As with all Park Tool taps, these are made of high carbon steel and are precision ground. Compatible with conventional tap handles.
