Core RC M3 Thread Repair Kit (pk10) CR904

These brass inserts are a strong solution to fix stripped threads anywhere 3mm screws are used in plastic. . Simply drill out the plastic with the included 4mm drill bit and insert the brass insert into the plastic. As you tighten the screw the insert expands providing a tight grip. . For an even stronger repair apply a drop of super glue being careful not to get any onto the internal thread.
