High Performance Inserts, Aerospace - Military
Inserts are stocked or manufactured to meet the demanding quality, performance and reliability requirements of today's applications. Every insert is advanced engineered with sophisticated manufacturing and strict quality control. Both the inserts and studs provide excellent torque-out and pullout capabilities through integral locking stakes which are driven into the parent material.
Solid Wall Staked Inserts
 Features - Provide excellent resistance to torque-out and pullout. Integral stakes are driven into the parent material to mechanically lock the insert in place and prevent rotation under high torsion loading and extreme vibration. Prevailing torque self-locking threads are integral to the insert or through the use of a polymer washer incorporated into the insert. Locking stakes are available in number of materials including self-broaching materials to eliminate pre-broaching in hard materials such as Alloy steels, Inconel, Titanium and WASPALLOY(TM).
Applications - Staked inserts can be used to enhance thread life and performance in soft materials such as Aluminum and Magnesium. They also provide increased torsion load capabilities. Ideal for electronics, aircraft engines, military defense systems and vehicles as well as overall thread repair, maintenance and salvage of expensive castings and forgings.

Ring Locked Inserts
 Ring locked inserts use the same locking concept as the Rosan ring locked studs, and provide an internal thread with the primary function of transferring high loads into weak base materials. They are used in initial design as well as to repair stripped threads in the parental material. Versions are available with an optional internal thread-locking feature.
Variations of the standard design include inserts with a captive lockring, with floating nut elements, vespel lock, blind, hydraulic and a solid version for relocation of misaligned holes or threads.
- Oversize replacements are available in every standard configuration.
- Inserts and lockrings are made from many different materials with varying finishes.
- Self-Broaching lockrings have been developed for use in materials with hardness of up to 40 HRC.
- Internal thread sizes range from 0.112 to 3.000(inch) and 3 to 45(millimeter)
- Parts are covered by "DOD", "MS", "DIN", and "LN" standards.
