Heli-Coil inserts are uniquely designed to protect and strengthen tapped threads in any material, and they offer many benefits, many of which will be discussed in the following blog. One benefit of using Heli-Coil inserts is that they create stronger assemblies due to the fact that they are inherently flexible, which helps strengthen tapped threads and provide a more balanced distribution of dynamic and static loads throughout the length of thread engagement. Their flexibility also compensates for variations in lead and angle error which allows each coil to carry its portion of the load. Another benefit of using Heli-Coil inserts is that they resist corrosion by minimizing galvanic action within a threaded assembly. Additionally, five insert lengths are available in every thread size so that bolt tensile strength may be balanced against parent material shear strength, assuring the bolt will fail before the parent material experiences damage.
