For those who may not know, Grade 8 is not always better than Grade 5 for all applications. In simple terms, as forces build on a bolt, a Grade 5 may bend and deform before a Grade 8. But as the force build more, the Grade 8 may snap while the Grade 5 only deforms more. The question of which is better depends on the application. In some cases its better to have a bent bolt than risk having a snapped one.


While 8s are technically more 'brittle' than 5s a grade 5 will bend and break before a grade 8 bends. Never use anything less than grade 8 on stressed suspension components.
