Most pedal-thread problems aren't strip damage. They're paint overspray after a crank refinish, a fine layer of corrosion after winter storage, or a thread that picked up a small burr from rough handling. The thread looks intact and mostly works, but the pedal threads in gritty or stops short of bottoming out. The Pedal Tap Set 1695.1 chases the thread and clears the obstruction without cutting new metal.

The 1695.1 is a thread-chase tap set, one for each side (left-hand and right-hand). The cutting edges follow the existing 9/16" × 20 TPI thread pitch and major diameter and remove paint, corrosion, or burred material; they don't cut new threads. If the existing thread is intact, the chase restores the clean feel.

When to chase, when to ream

Chase if:

• The existing thread is intact (you can see the thread profile, the bolt threads in even if reluctantly)
• The damage is paint, corrosion, light burrs, or accumulated dirt
• The pedal threaded in correctly on first install but now stops short or feels gritty

Ream (with the left or right reaming tap) if:

• The thread is stripped (the bolt cuts new thread into the surrounding alloy)
• The thread was cross-threaded at first install
• The thread is torn out at the entry, with the crack visible

Chasing a stripped thread won't fix it; there's no material left for the chase tap to clean. Reaming an intact thread cuts good metal away unnecessarily.

Pair with the handle

The 1695.1 mates to our Handle for Pedal Taps 1695/4BI via the standard square-shank interface. The handle's magnetic-collet engagement holds the tap perpendicular to the crank face during the chase, which keeps the cleaning action consistent across the full thread depth.

What this is NOT

The Pedal Tap Set is a thread-chase tool. It is NOT a pedal install-aid (that's the Pedal Genie, a completely different product; see our broader catalog). It is NOT a thread-cutting tool for stripped threads (that's the reaming taps). Conflating these workflows is the most common shop error in pedal-thread service.

Specs

• 9/16" × 20 TPI thread chase
• Left-hand and right-hand versions in the set
• Square-shank engagement, compatible with 1695/4BI Handle for Pedal Taps
• Article number: 1695.1

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The 1695 family is one of those workshop-tool sets that has its origin in Unior's machinist-tool catalog (general-purpose thread taps) and was specifically adapted to the cycling repair workflow. Pedal-thread service is the most common bicycle-thread rescue a working shop does, which is why the dedicated tap set earned its place in the catalog.

Pro tip from our mechanics

A pedal that goes in cleanly on the first turn rarely needs a chased thread. A pedal that resists or feels gritty does. Chasing the thread before forcing the pedal saves the crank arm; forcing the pedal through a partially obstructed thread is how a chase-able thread becomes a ream-able one.
