• Reinforcing worn or weak receiving threads in service parts, housings and repeatedly assembled joints
• Using one matched repair set when you need process consistency for the stated thread designation
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: cắt ren, taro lại ren, and làm sạch ren depending on condition

Lưu ý Select the product by thread designation, workpiece condition and the holder concept used in your process.

• Matched repair logic supports repeatable restoration of an existing thread designation
• Insert based repair can improve service life of the receiving thread in repeated assembly work
• Suitable for maintenance, overhaul and workshop repairs where part replacement is undesirable
• Clear assignment between preparation, tapping and insert installation reduces handling errors

• It is a repair system and not the fastest choice when you only need a one time emergency fix without the full preparation steps.

1. Secure the part and identify the damaged thread so that the repair axis is clearly accessible.
2. Prepare the hole with the matched drill from the kit and remove loose chips from the bore.

4. Clean the prepared receiving thread and check that the entry is free from debris.
5. Load the wire insert onto the Dụng cụ lắp ren cấy and start it square to the prepared thread.
6. Drive the insert until it sits at the intended depth in the receiving thread.
7. Remove the tang where required and check the repaired thread with the intended fastener or inspection method.
