Key-Locked/Staked Inserts

KEY-LOCKED / STAKED INSERTS / KEENSERTS®

Solid, one piece key-locked inserts and studs provide high resistance to torque-out and pullout in applications. To prevent rotation due to torsion or vibration, preassembled keys are driven down through the threads of the parent material mechanically locking the fasteners into place.

These products are superior for use in soft materials such as aluminum or magnesium when extra strength, extended thread life and vibration resistance are required. They have the option of self-broaching keys for hard material applications and are available with a variety of locking devices.

 

Floating inserts automatically compensate for misalignment of mating holes and are particularly useful on curved surfaces.
