Helical thread repair inserts are designed to repair worn threads inside tapped holes. They provide reliable threading in metals, composites, wood or similar materials. Raptor Supplies offers a wide range of thread repair inserts by Heli-Coil, Powercoil and Chrislynn. They are ideal for the automotive, electronics, aerospace, shipbuilding & power generation industries and are used for repairing, recreating or reinforcing stripped bolt / screw threads to withstands higher torque.
Some thread inserts have a slightly larger diameter than the diameter of the tapped hole before installation, as the installation tool decreases the leading coil's diameter when it applies torque to the insert's prong / tang for easy installation. Once the threaded insert is installed, it acts like a spring and expands outward onto the material for strong anchoring.
The helical insert length should be at least as long as the desired screw diameter. Users may also choose inserts having longer lengths for increased strength. The exact insert length can vary, depending upon the application & the material. Materials like steel do not need long inserts, but for soft materials like aluminium, a longer insert is preferred.
Yes, some thread inserts can be removed using removal tools that attach to them & unwind them in the direction opposite to that used during installation.
