Thread Repairs  Cylinder head bolt thread repair being carried out on-site with engine in place

At Precision, we do not use traditional heli-coils to repair threads as they are inferior quality to the products that we use.  Our thread repair system is the ultimate way to repair threads in stripped or damaged holes.

The thread repair we carry out uses a solid bushing insert. This guarantees easy installation and allows for full load use of tapped hole, ensuring protection against stress and vibration.

They are thin walled due to synchronized internal external threads. Thin cross sectional area allows for installation in areas of limited space and clearance material. 

Having a flange on the top of the insert also insures that the insert will have positive placement and cannot wind down into the newly repaired hole.

Thread repair insert being fitted On installation the bottom internal threads of the insert are cold rolled to expand the mating external threads into the base material locking the insert in place. Locking mechanism is at the bottom of insert.
