Pedal Tap Set

This set is designed specifically for standard 9/16" x 20 TPI threading, which is the industry standard for most modern adult bicycles. It will not work on older or specialized cranks that use different thread sizes, such as half-inch pedals found on some children's bikes or vintage equipment.

Yes, you will need a tap handle or an adjustable wrench to turn the taps. Since these are standard-sized taps, most shop-grade tap handles or large adjustable wrenches will provide the necessary leverage to cut or clean the threads effectively.

Bicycle pedals use different threading for each side to prevent them from loosening while riding. The right-side pedal uses standard right-hand threads, while the left-side pedal uses reverse left-hand threads; having both taps ensures you can service both crank arms correctly.

These taps are primarily designed for chasing or restoring damaged threads, not for cutting new threads into a blank piece of metal. If your crank arm threads are completely stripped or missing, you may need to install a thread insert (like a Helicoil) first, which requires a larger drill bit and tap.

Absolutely. Carbon steel is the industry standard for this type of tool because it is hard enough to cut through aluminum crank arms without dulling quickly. Unior backs this set with a lifetime warranty, reflecting its durability for frequent, professional maintenance.
