Reliable Thread Restoration – thanks to M9 x 1.25mm Heli Coil inserts
Heli coil style wire inserts are sized for M9 x 1.25mm threads and are installed after drilling and tapping the damaged hole. The coil provides a new internal thread surface that engages fasteners where original threads have failed.
Restores stripped metric threads to a secure, factory-compatible profile so bolts and studs can be tightened reliably in engine and chassis applications.
Durable, Corrosion-Resistant Repairs – with precision stainless steel wire
Inserts are formed from precision stainless steel wire, chosen for strength and water resistance. Material resists common workshop environments where moisture and oil are present.
Repairs hold up better than re-cut soft metal alone, reducing the chance of repeat stripping in service conditions such as engine bays.
Workshop-Ready Convenience – with a full set of installation and finishing tools
The kit includes a twist drill bit, thread tap, installation tool, lug breaking tool and hex key wrench to prepare, place and trim inserts. The installation tool has a rubber handle to reduce slipping during use.
Everything needed to complete multiple M9 repairs is included, avoiding trips to source extra taps or holders and saving time in routine workshop repairs.
