Need clarity on Bonding bushings/locknuts

[eagle]

When using metal nipples or conduit between meter & Main service panel are the regular locknuts that have the small biting teeth on them to reduce reversal potential acceptable as a means of bonding or is a bushing or locknut with a tap screw or jumper strap required ?

250.92(B) ... Standard locknuts or bushings shall not be the sole means for the bonding required by this section.

Standard locknuts or bushings are insufficient. See 250.92(B)which spells out acceptable means of bonding at services.

you could use a bonding locknut which is listed for the purpose. They have a bonding screw that tightens down against the threads after they have been tightened.
