Application: Porsche® 928 1978-1984 with Head Studs
Do not re-use your fasteners! The metal in the fasteners will fatigue the second or third time they are torqued, and you will not get a true torque out of a used fastener. The result can be an early head gasket failure.
ALSO: Our hi-strength alloy Head stud nuts are thicker than OEM, to catch and hold more threads.
NOTE: These nuts are designed for use with the stock OEM head studs. We also sell replacement head stud kits that include all the nuts needed.
One kit includes: 20 alloy head stud nuts.
