Keenserts® inserts and studs
Keenserts® inserts and studs are designed to provide high resistance to torque-out and pull-out loads. Pre-assembled keys are driven down through the threads of the parent material to mechanically lock the fasteners into place. The inserts are available with free-running threads or with various types of locking features, including crimp threads, Vespel™ insert and beam lock. The studs provide a nut-end thread designed to transfer high axial loads into ductile base materials. The stud or keyed end is installed into the parent material, eliminating the need for removing or replacing a bolt.
