These replacement jaws and the spring are spare parts for a tap holder with ratchet when the clamping mechanism no longer holds the tool square reliably. Use them for maintenance of the holder, not as a cutting tool. Select the spare parts by the holder type, the ratchet design, and the stated size No. 2 / 20.
Stable jaws and a working spring help the tap holder clamp the square shank consistently during manual threading. Before replacement, check whether the holder body and guide surfaces are still in good condition because worn holder geometry cannot be repaired by replacing the jaws alone.
- Replace worn clamping jaws and the spring in a compatible tap holder with ratchet.
- Use during holder maintenance when the inserted threading tool has play or the jaws close unevenly.
- Support secure clamping of threading tools with a square shank in the matching holder size.
- Check the holder body, guide surfaces, and ratchet function before installing the spare parts.
Note Use the spare parts only when the holder type and size match the tool holder that you want to maintain.
- Targeted replacement restores the clamping contact parts without replacing the complete holder.
- New jaws reduce play between the holder and the square shank when the holder body is still serviceable.
- The replacement spring supports repeatable jaw movement after reassembly.
- The 10 piece quantity supports workshop maintenance where holders are used frequently.
Drawbacks
- Replacement parts cannot compensate for a cracked holder body or damaged ratchet mechanism.
- Installation requires careful handling because small parts can be lost or fitted in the wrong position.
- Remove the threading tool from the holder before you open the clamping area.
- Place the holder on a clean surface where small parts cannot roll away.
- Observe the position of the old jaws and spring before removing them.
- Remove the worn jaws and the spring without forcing the holder guides.
- Clean the guide surfaces and remove chips, oil residues, and abrasion.
- Insert the new spring in the same functional position as the old spring.
- Fit the jaws and check that both sides move freely and close evenly.
- Clamp a suitable tool and perform a short functional test before regular use.

- How do you know that the jaws should be replaced?
- Replace the jaws when the tool has noticeable play, the clamping contact is uneven, or the square shank no longer sits securely in the holder.
- Do these spare parts repair every tap holder with ratchet?
- No. The spare parts must match the holder type and the stated size No. 2 / 20.
- What should you check before installation?
- Check the holder body, jaw guides, and ratchet mechanism because replacement jaws only help when the surrounding holder geometry is still usable.
- Why is the spring important for clamping?
- The spring supports defined jaw movement and helps the clamping parts return to a stable position during holder operation.
- Can poor clamping damage a threading tool?
- Yes. A tool that slips or tilts in the holder can damage the square shank and can make the thread start less controlled.
