Park Tool TAP-12.3 Thru Axle Tap

The TAP-12.3 is designed to clean or restore damaged threads in bicycle thru-axle dropouts. It ensures your thru-axle threads are smooth and clear, which prevents cross-threading and ensures your axle installs securely.

Yes, this tap is designed to be used with a standard tap handle. It does not come with a handle, so you will need to secure it into a compatible tap wrench or handle to provide the leverage needed for the job.

This specific tool is sized for standard thru-axle dropout threads. Before purchasing, verify the thread pitch and diameter of your frame's thru-axle to ensure compatibility, as thru-axle standards can vary between manufacturers.

While it is capable of cutting threads, it is primarily intended for chasing or cleaning existing threads that have become damaged or clogged with debris. If you are attempting to modify a frame, proceed with extreme caution to ensure you do not remove too much material.

Because it is made from high-carbon steel, it is important to keep the tool clean and dry after use to prevent rust. A light coating of tool oil before storing it in a dry place will help maintain its precision and sharpness for future projects.
