These GRADE 10 studs and nuts replace the factory camshaft housing/cam tower bolts on the Oldsmobile, Pontiac, and Chevrolet car equipped with the 2.3 Liter Quad4 OHC/DOHC and 2.4 liter Twin Cam DOHC engines. Often when repairing the 2.3 Quad4 and 2.4 Twin Cam engines, during the camshaft housing/cam tower final torque sequence, the factory steel bolts will strip the threads in the aluminum head. Using these repair studs you can typically continue the repair without removing the cam housings or the cylinder head.
