Abstract
In a preferred embodiment, a driver socket is configured to provide a visual indicator on a portion of a locknut upon application of a predetermined torque to the driver socket relative to the locknut. The driver socket has a member which is positioned proximate to the first end, with a portion thereof protruding into an aperture of the driver socket. The member is configured to engage a drive configuration of a locknut in order to apply nut torque to the locknut upon rotation of the drive socket and to form a mark on the drive configuration of the locknut in order to provide a visual indicator on the locknut that the locknut has been subjected to the desired torque during initial assembly. The driver socket is preferably attached to a ratchet arm of a fastening tool which provides a mechanical advantage in applying the desired torque.
