KEENSERTS Important Information
KEENSERTS® inserts for maximum reliability for your screw connection
KEENSERTS inserts are solid precision threaded inserts and they offer high reliability in their application.
They are used in the whole industry, from tooling, marine, train, defense technology, clean room applications to aerospace.
Especially for lightweight designs, they are increasingly a major factor for realizing connections with high strength despite lightweight design materials.
KEENSERTS inserts can be used in virtually any material and prevent in their screw connection the overloading of the nut thread.
KEENSERTS inserts are pre-mounted so there are no loose parts to compromise safety. In a variety of applications from initial assembly to repair applications, KEENSERTS inserts have proven themselves millions times over.
Why KEENSERTS® inserts?
The functional concept of KEENSERTS inserts is based on an increase in the surface area of the thread to enable a higher screw force. This allows higher loadable threaded connections in workpieces with lower strength. Tests have shown that already a 20% higher pull-out value can be reached with the standard version of our KEENSERTS inserts. For all designs and variants of KEENSERTS inserts, pre-mounted „KEES“ are pressed into the surrounding material, thus creating a reliable rotation prevention. KEENSERTS inserts are vibration-resistant and highly loadable.
KEENSERTS inserts are available with both metric and inch thread dimensions SAE AS 8879.
Always a perfect installation
No special skills are required for the installation of KEENSERTS inserts. Installation can be learned in a very short time. Thread damages are impossible during the installation process. Hand tools as well as hydropneumatic and battery-operated processing devices adjustable process
parameters are part of the delivery program.

In case of replacement
If a KEENSERTS insert needs to be replaced, this can be done in the same mounting thread. The existing thread does not have to be reworked.
The perfect material and the right coating for your application
KEENSERTS inserts are in the standard version made of passivated A1- steel and are pre-assembled with locking chocks, the so-called „KEES“. Depending on your requirements, other materials are also available for the threaded bodies.
A standardized system for all types of threads
In addition to the standard version, we offer a heavy variant with enlarged external thread for particularly high load cases. Almost all versions are also available with an more jamming additional threadlocker. KEENSERTS inserts are available in many different versions to meet the various
requirements. There are KEENSERTS inserts as threaded studs or KEENSERTS inserts with a closed bottom. If you require radial tolerance compensation in your assembly, KEENSERTS inserts are available as a so-called „floating variant“.
KEENSERTS inserts are alternatively available with metric or imperial thread dimensions.
