Abstract：Key-locked insert is a new-style fastener for screw threads, which has many advantages such as convenient
installation, reliably connection, easy disassembly, can solve some problems in use of wire thread insert. Combining with
the working experience, the structural characteristic of the key-locked insert and its installing principle are introduced. The
method of installation, technological parameter and application effect on the resin matrix composites are also discussed.
The results of application indicated that to use technology of pneumatic punching press can safety assembly, high installation
efficiency and easy disassembly in the resin metrix composites.
