^used them before, they don't really work well as i've found they deform under pressure
i was unable to torque them up to 80ft-lbs before deforming

there was a type of lug lock nut that i found should work, project kics i think as their seat moves independently to the nut so it should push on to the washer instead of forcing it's way though it
don't take my word for it though, i never could justify splashing out on kics
