how to insert tangless helicoils?

Installing tangless helicoils is a straightforward process when you follow these steps. Tangless helicoils are used to repair or reinforce damaged or stripped threads in various materials, such as metal, plástico, or composite surfaces.

Materials and Tools:

1. Tangless helicoil insert
2. Tap (matching the size of the helicoil)
3. Drill bit (matching the size specified for the helicoil)
4. Installation tool (specifically designed for tangless helicoils)
5. Threadlocker (opcional)
6. Ratchet or wrench (for the installation tool)
7. Calipers or depth gauge (for measuring hole depth)

Etapas de instalação:

1. Faça o furo: um. Choose a drill bit size as specified in the tangless helicoil kit. The hole size should match the external diameter of the helicoil insert. b. Carefully drill a hole into the damaged or stripped threaded hole to the required depth. Use a depth gauge to measure the hole depth accurately.
2. Tap the Hole: um. Select a tap that matches the thread size and pitch of the tangless helicoil insert. b. Begin threading the tap into the drilled hole. Make sure to keep it straight and aligned with the hole. c. Tapping should create fresh, clean threads that match the tangless helicoil insert.
3. Prepare the Helicoil: um. Unwind the tangless helicoil from its packaging and insert it into the installation tool. b. Ensure the helicoil is the appropriate length for the tapped hole, with a small portion protruding.
4. Insert the Helicoil: um. Insert the helicoil, with the installation tool, into the freshly tapped hole. b. Rotate the installation tool clockwise (righty-tighty) to thread the helicoil into the hole. c. Keep turning until the helicoil is fully seated and flush with the surface.
5. Remove the Installation Tool: um. Carefully unscrew and remove the installation tool from the installed helicoil.
6. Check and Adjust: um. Inspect the newly installed helicoil to ensure it’s flush with the surface and properly seated. b. If needed, use a threadlocker on the helicoil to secure it further in place.
7. Test with a Fastener: um. Confirm the repair by threading a matching screw or bolt into the helicoil. It should go in smoothly and securely.
8. Final Adjustments: um. Make any final adjustments to the installed helicoil if necessary.

Tangless helicoils are designed to be self-locking, so they don’t require the tang removal step that is necessary with traditional helicoils. The installation tool helps keep the coil in place while you thread it into the hole.

Always refer to the manufacturer’s instructions and guidelines for the specific tangless helicoil kit you are using, as the process can slightly vary based on the manufacturer’s recommendations. Proper installation is crucial for the helicoil’s performance and the quality of the repaired or reinforced threads.
