Additional joint strength in low tensile materials such as aluminum, magnesium and plastics.Self-locking internal threads.T-Sert inserts require no locking rings or other separate locking devices. An integral, self-locking element extends longitudinally through the wall of the insert, and provides simultaneous locking action for both internal and external threads in accordance with MIL- I-45932. The torque developed by the T-Sert locking element provides approximately twice as much torque on the external as on the internal diameter, precluding the possibility of unintentional rotation after installation.During installation of the mating fastener the T-Sert self-locking element flows into the thread root, forcing the fastener threads into metal-to-metal contact with the threads of the T-Sert insert, thus holding it securely. Because the T-Sert locking action is prevailing, and does not depend upon the seating of the mating fastener, it does not loosen with severe vibration or shock. Mating fasteners need no lockwashers, adhesives or lock wiring or any other expensive additional devices.

Long-Lok strip fasteners are universally accepted, prevailing torque type self-locking fasteners, with excellent vibration resistance. Over 45 years of use in thousands of proven applications attest to the wide acceptance of the Long-Lok strip. These fasteners are available in a wide range of sizes from miniature eyeglass screws to fasteners for the heaviest of highway equipment.
