M8 x1.25mm Thread Repair Insert Kit Compatible Hand Tool Set for Auto Repairing, Rocaris 30 Pcs Thread Repair Kit
#adRocaris #ad - Don't work against the thread direction as the tang could break. Wind the insert in with a light downward pressure until a half turn below the surface. To repair a spark plug thread no pre-drilling is necessary if using the special spark plug tap, please pay attention that for fluteless taps bigger holes are required.Due to the narrow and exact tolerances the new thread normally is stronger than the original ones.
More information #ad
Tang removal - after finishing lift the installation tool and use the tang break tool to remove the tang. Drilling - clear the damaged threads with a standard drill. Tapping - use the special taps for cutting the holding thread into the cleared hole recommended to use a suitable cutting oil. For bigger sizes and spark plug taps use long nose pliers to remove the tang. Checking - check that the thread and pitch of the tap and the bolt match. Install the insert - place insert on installation tool and position the adjustable ring so that the insert tang is centered in the tang slot.
