Spark Plug Thread Repair Kits

Kits include helical inserts, a tap, and an installation tool. Also known as Heli-Coil inserts, they have coils that expand once installed to securely anchor the insert. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes. Remove the prong to insert the screw.

Black-Phosphate Steel Easy-to-Install Thread-Locking Inserts

A black-phosphate finish provides mild corrosion resistance. Also known as E-Z Lok, these inserts use Loctite® adhesive to keep them in place. The adhesive reaches full strength after 72 hours. Installation requires a drill bit and a standard tap. Then set the insert with a bolt and two nuts, or use an installation bit.

Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole.
