RUKO bolt breaker M4 thread, high strength steel, 4 mm diameter.

The Ruko-244164 M4 Threaded Bolt Breaker is an essential tool for repairing damaged threads. This device restores the functionality of screws and bolts, ensuring a secure and long-lasting fit. Its use is simple and based on a four-step process: drilling, tapping, mounting the threaded sleeve, and breaking the pin. To begin, the damaged thread must be drilled using a RUKO twist drill bit, ensuring that the tap and the threaded bolt from the ProCoil set match in thread and pitch. Next, the new retaining thread is cut using a tap, preferably with cutting oil to facilitate the process. The threaded sleeve is then mounted on the screw-breaking tool, ensuring that the retaining pin is properly seated. Finally, the retaining pin is broken with the pin breaking mandrel, thus completing the installation of the new thread.
