Abstract: A fastener system that includes a fastener, a compression-limiting sleeve, and a retainer which generally retains the compression-limiting sleeve on the fastener. By providing that the compression-limiting sleeve is not staked to the fastener, existing technology can be used, and no extra staking processing step needs to be performed. The fastener may comprise a conventional metal threaded screw or bolt, possibly having a recess in its head for receiving a driver. Preferably, the compression-limiting sleeve is cold headed as opposed to being stamped, and preferably includes a counter bore which assures that an end of the retainer is below an end surface of the compression-limiting sleeve. Preferably, the retainer is formed of a thermoplastic elastomer or another suitable material.

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.
