Helicoil Free Running Inserts
Helicoil free running inserts were developed specifically for the aerospace market over 75 years ago, and have since evolved to be an essential solution for failing threaded assemblies in many industries, such as electronics, automotive, communication, and defense & energy industries. Helicoil free running inserts are designed to improve the overall strength of a worn or damaged threaded hole. Today's improved design offers superior performance, and a wide range of high quality Helicoil free running inserts and installation tools are produced to meet the demanding needs of designers and manufacturers.
