ok i see well lewts say if it is 120/240 and you dont use all the syntrics on the service equiptment dont you have to use a bonding bushing and a bonding locknut

Yes. For line connections of service conductors. Here is a quote from a UL newsletter.

Bonding at Services
NEC Section 250.92(B) is applicable to bonding
at services, and in part states, “Bonding
jumpers meeting the other requirements of
this article [Article 250] shall be used around
concentric or eccentric knockouts that are
punched or otherwise formed so as to impair
the electrical connection to ground.” For
services, this confirms that bonding jumpers
are required unless all concentric or eccentric
knockouts have been removed.
