Replacement cylinder stud kit M8-1.25. Strong Grade 8.8 steel studs.
4 studs, 4 flat washers, 4 lock washers and 4 nuts. All the parts in a very convenient kit.
Please verify your current engine stud size before ordering.
Determine the size you have: 6mm will be the same as engine mounting studs, M8-1.00 will be larger but will still have the same thread spacing when compared side by side with mount studs. Another simple way is to measure 1 cm and count the threads. 1.00 thread pitch will have 10 threads in that 1 cm, 1.25 thread pitch will have 8 threads.
