Park Tool TAP-3 Pedal Tap There's nothing more frustrating that stripping out or cross threading a set of brand new cranks. It's frustrations like these that inspired Park Tool to make the TAP-3 Pedal Tap Set. It includes two of their precision machined taps for 1/2" x 20 TPI threads on right and left cranks. They're made of high strength steel, and fit all conventional tap handles.
