The keys that are pre-assembled onto each fastener are driven down through the threads of the parent material mechanically locking it into place. These keys positively prevent rotation due to torsion and vibration. Keenserts inserts are available with internal threads that are either free-running or come with locking devices such as deformed threads Vespel insert or beam lock. Inserts are also available with the unique patented Spiralock thread form which allows for a free running bolt installation. Once the mating bolt preload is applied Spiralock inserts will resist the most severe transverse vibration. Keenserts studs provide a nut-end thread designed to transfer high axial loads into weak base materials. The stud or keyed end is installed into the parent material thus eliminating the need for removing or replacing a bolt. Keenserts inserts and studs are easy to install using standard drills taps and gages. Alcoa Fastening Systems offers a wide selection of manual and power installation and removal tools. Both inserts and studs come in a variety of materials including 303 304 A286 and 17-4 PH Corrosion Resistant Steels along with Inconel 718 Nickel-Chromium Alloy 6Al-4V Titanium 4140 Alloy Steel and Carbon Steel. Locking key materials consist of 302 A286 and 420 Corrosion Resistant Steels as well as Inconel X-750 and Inconel 718 Nickel-Chromium Alloys. Variations of the standard insert include miniature lightweight heavy duty .
