ROCKCRAWLER.com - Grade 5 vs. Grade 8 Fasteners

Fasteners are very important. Cheaping out on them is really a waste of time. Also, I know with all modern car engines and I assume bike motors, once you take off a factory head fastener/block bolts etc, you should ALWAYS use new bolts. They are only made to be torqued/stretched once. Not like in the old days when car engines used big bolts with lots of extra margin. Now it is single use sized. Oh well......

Lots of new stuff is TTY anyway and cannot be reused
