Tork Craft NR5012-03 Replacement Inserts M12 X 1.75 X 24mm 2D 5pc
At a Glance: 5 replacement stainless steel M12 x 1.75mm thread inserts, 24mm long, for the Tork Craft NR5012 internal thread repair kit.
The Tork Craft NR5012-03 Replacement Inserts are designed for use with the Tork Craft NR5012 M12 x 1.75 internal thread repair kit. These inserts are used to repair damaged, stripped, worn or over-used internal M12 threads, restoring the hole so that the original M12 x 1.75mm fastener can be used again.
Manufactured from stainless steel, these 2D replacement inserts create a strong and durable internal thread surface once installed into a correctly drilled and tapped repair hole. The 24mm insert length makes this pack ideal for deeper M12 thread repairs where a longer thread engagement is required.
This pack contains 5 replacement inserts for continued use of the NR5012 repair kit. The 2D length gives extra thread depth compared with 1D and 1.5D inserts, making it a practical option for applications where a longer and more secure repaired thread is preferred.

Extra Information
- NR5012-03 is the 2D replacement insert pack for the Tork Craft NR5012 M12 x 1.75mm internal thread repair kit.
- 2D means the insert length is two times the thread diameter. For M12, this gives an insert length of approximately 24mm.
- This insert length is longer than the NR5012-01 12mm 1D insert and the NR5012-02 18mm 1.5D insert.
- These inserts are used only after the damaged hole has been correctly drilled and tapped using the correct thread repair tools.
- The inserts are for internal thread repair and are not used for cutting external threads on bolts or rods.
- Always confirm the available hole depth before selecting a 24mm insert.
Pro Tips
- Use the 24mm 2D insert when the application allows for deeper thread engagement and a longer repair length.
- Before installation, check that the hole is deep enough for the full insert length and the fastener being used.
- Always clean the tapped hole properly before installing the insert. Swarf or dirt can prevent correct seating.
- Use the correct installation tool from the NR5012 kit and wind the insert in carefully to avoid damaging the coil.
- Install the insert approximately 1/4 to 1/2 turn below the surface where possible for a neat finished repair.
- Break off and remove the tang after installation before fitting the bolt.
How to Use
- Confirm that the damaged internal thread is M12 x 1.75mm and that a 24mm 2D insert is suitable for the repair depth.
- Use the correct drill and STI tap from the NR5012 thread repair kit to prepare the damaged hole.
- Clean the tapped hole thoroughly to remove chips, swarf and loose material.
- Fit the replacement insert onto the installation tool from the NR5012 kit.
- Wind the insert into the tapped hole using the installation tool until it is correctly positioned.
- Use the break tool to snap off the insert tang.
- Check the repaired thread by carefully threading in the correct M12 x 1.75mm fastener by hand before final assembly.
