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.

Kelox® inserts and studs are high-performance threaded products that typically require smaller diameter installation holes than other solid bushing inserts and studs. This translates into overall reduced boss sizes and weight savings. The Kelox® fasteners incorporate a pair of keys joined by an integral ring that facilitates the driving of the keys into the structure.

Ring locked inserts and studs have superior torsional resistance in both hard and soft parent materials. Inserts are available with locking and non-locking threads.

Slimsert^™ inserts have a thin cross section, which is ideal for installation into applications requiring minimum boss configurations. This allows for reduced casting weight while adding strength. The upper end of the insert is swaged into the counterbore wall of the parent material and locks it into place.
