ROSAN® product portfolio includes a complete range of high quality ring locked inserts & studs with superior torsional resistance in hard and soft parent materials as well as various other fittings, inserts & studs designed for a variety of high specification applications. Their ring locked inserts & studs come standard with an oversized pitch diameter on the thread mating with the parent material & resulting in a slight interference fit, especially advantageous in high vibration and/or fatigue environments. Ring locked inserts are available with internal threads, either free-running, or with locking devices such as deformed threads, Vespel™ insert, or beam lock. Ring locked products are easy to install with the use of standard drills, taps, gages and offered installation and removal tools. Both inserts & studs come in a variety of materials including 303, A286, and 17-4 PH Corrosion Resistant Steels (CRES), Inconel 718 Nickel-Chromium Alloy, 6Al-4V Titanium, and 4130 Alloy Steel. Lockring materials consist of 303 and A286 CRES, and Inconel 718.Variations of the standard insert design include blind, hydraulic, solid and captive lockring. Stud variations include size-on-size, pin types, hydraulic, terminal, full shank, and reduced-shank nut ends. A complete line of unified and metric products is available, along with oversize replacements for repair of damaged parent material.
