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.
Heli-Coil inserts possess a number of additional benefits, including that they eliminate stress because the outward spring-like action of the insert is able to hold the parent material in place, so there is no staking, locking, swaging, or keying. Moreover, these inserts allow for the use of smaller bosses, flanges, and fasteners than with any other insert because they can be incorporated into existing designs where no provisions have been made to hold an insert, meaning the boss size does not have to increase. Heli-Coil inserts also have overall lower component costs, lower installation costs, and increased design flexibility which allows for you to select the proper parent materials while still maintaining maximum threaded assembly
strength with a budget in mind. Because these inserts feature a mirror-smooth surface finish, it is possible to use minimal wrench torque while experiencing maximum clamping action and bolt tension. Tolerant of a wide variety of temperatures ranging from -320 degrees Fahrenheit to +800 degrees Fahrenheit, these inserts are durable enough for use in countless applications.
Moreover, Heli-Coil inserts are available in versions that are mounted on plastic strips and wound onto reels with 500 to 1000 present in each reel. Power installation tooling increases their installation rates because they help to minimize the amount of handling necessary. They are universally accepted and have been tested for tension, torque, shear, vibration, and fatigue by leading American companies, as well as the United States Armed Forces. Confidence in the performance and reliability of Heli-Coil inserts is high because of their use in aviation, electronics, industrial, automotive, and military equipment applications.
Three different types of locking inserts are available depending on the application they are used in. First, screw lock inserts have positive self-locking torque which makes them resilient locking mechanisms. More than that, it is possible to repeatedly assemble and disassemble them without losing self-locking torque. Screw lock inserts also help save space, weight, and money because they eliminate the need for lock wiring, lock washers, chemical compounds, plastic pellets/patches, and other locking mechanisms. Next, high torque inserts have a higher prevailing torque than screw locks which compensates for their reduced friction in lubricated applications. That being said, they are frequently utilized in applications with higher vibration. Finally, stud lock inserts possess the highest prevailing torque, and they allow for the use of threaded rods to save space in stud applications. Furthermore, they can be fitted to any class of threaded rod and prevent consistencies which are caused by interference fit studs.
