Right Pedal Thread Inserts, 10-Pack

The Right Pedal Thread Insert 1695.3A is the rescue part for a stripped right-hand pedal thread. The insert installs into a freshly reamed crank arm hole and accepts a standard right-hand 9/16" × 20 TPI pedal. After the thread locker cures, the crank takes the original right-hand pedal at full working torque.

The "right" designation matters: the right pedal threads in the standard clockwise direction, and the insert's inner thread is sized to match. The Left Pedal Thread Insert handles the left-hand pedal thread (which is reverse-threaded by bicycle convention to prevent loosening under pedaling).

How the insert sits in the rescue workflow

The complete rescue:

1. Ream the failed thread. The 1695.1AR Right Reaming Tap cuts the failed thread away and cuts a new thread pattern sized for this insert. Use the Handle for Pedal Taps 1695/4BI for leverage and alignment.

2. Thread-lock the insert. Apply a strong thread locker (green or red typical) to the outer thread of the insert.

3. Install the insert into the reamed hole. Hand-thread until flush with the crank face. Don't over-torque; the locker does the holding work.

4. Cure. 24 hours typical for a strong cure. The pedal can be installed normally after curing.

Material and form

The insert is a solid steel sleeve; not a spring-coil thread insert. The solid form holds the thread profile under cyclic load better than a spring insert; pedals see hundreds of millions of force-cycles over a working lifespan, and the insert's job is to stay rigid through all of them.

The outer thread is sized to match the cut profile of the 1695.1AR reaming tap. The inner thread is the standard 9/16" × 20 TPI right-hand pedal thread, identical to a stock crank's pedal hole.

What's in the pack

10 inserts per pack. A working shop uses inserts on every Crank Saver service; stocking by the pack is the working-shop economics.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. The 1695.3A is part of Unior's purpose-built pedal-thread-rescue system. The complete kit (taps, handle, inserts) is sold as the Crank Saver Kit for shops setting up the full workflow; individual components are stocked for shops re-supplying consumables.

Pro tip from our mechanics

The cure time on the thread locker is the most-skipped step in pedal-rescue jobs. A shop that installs the pedal "right away" because the customer is waiting often gets a callback for a loose insert two months later. A reliable pedal-rescue workflow includes the cure time on the schedule.

FAQ

How many inserts do I get for the price? Ten. The 1695.3A is sold as a 10-piece set, the same pack Unior supplies to shops. Each repair uses one insert, so a pack covers ten stripped right crank arms.

Will these fit a left crank arm? No. These are right-hand inserts with a standard clockwise 9/16" x 20 TPI inner thread. The left pedal thread is reverse-threaded by bicycle convention, so the left crank needs Unior's left-hand insert set (article 1695.4A).

Do I need a special tool to install them? Yes. The crank arm must first be reamed with the Unior 1695.1AR right reaming tap, which cuts the 5/8" x 24 TPI seat the insert's outer thread matches. The insert is then set with a strong thread locker and left to cure before the pedal goes back in.

Which pedals fit after the repair? Any pedal with the standard 9/16" x 20 TPI thread, which covers nearly all adult-bike pedals. The insert's inner thread is identical to a stock crank's pedal hole, and the pedal runs at full working torque once the thread locker has cured.
