What is the alternative to a HeliCoil insert? ›

However, key inserts provide an alternative to helicoils and they have their own set of inherent benefits and flaws. Key inserts became popular because of the ability to quickly repair stripped or damaged threads without having to discard the original part.

Heli-Coil^® Kits - Thread Repair Kits & Master Sets

Restore stripped threads easily and permanently with Heli-Coil thread repair kits and master sets. Heli-Coil application-specific thread repair kits make complex repairs manageable and are often the recommended solution by both domestic and foreign automakers.

One of the advantages of using a helical insert is that it increases fastener strength and longevity. Free-running coil inserts reduce stress and fatigue while maximizing thread strength and increasing reliability.

Keep in mind that the proper installation depth of a HeliCoil insert is 1/4-1/2 turn below the top of the original hole.

Another disadvantage of helical coil type inserts is that they are sometimes harder to fit than a solid bush. This applies especially In deep or inaccessible holes.

The tang is a small segment of the end of the insert that extends into the middle of the coil. With tanged inserts, the tool uses the tang to grip the coil and screw it into place. Once the helicoil is installed, the tang is broken off and removed.

The Time Sert, which was used to install the bolt on the right, is said to be a more durable tool than the Heli-Coil.

Use HELICOIL® wherever low shear strength materials – such as aluminium or aluminium-magnesium alloys – are used. In these applications HELICOIL® thread inserts generate heat-resistant, wear-resistant and high-strength thread of the highest precision. No internal thread wear, even with frequent use.

Helicoils can also be useful in materials which are a bit too soft to accept threads or for dissimilar materials. Because of manufacturing tolerances most thread standards tend to put the load on quite a small area of the thread and some materials are prone to galling threads.

No problem do not worry about a gap in the middle just don't put the bottom too close to the edge break out the Tang go ahead and feed the second one in if there's not enough room you have coils exposed that's not a problem either but you will require a dental separating disc used and sold for dremel type tool.

What is a free running helicoil? ›

Free running helical inserts have a thread that is smooth and free running. Locking helical inserts have the same characteristics as free running, but also allow frequent removal and reassembly of screws without appreciable loss of torque and positively secure threaded members against vibration or shock loosening.

HELI-COIL® Pipe Thread Inserts are precision formed screw thread coils of 18-8 Stainless Steel wire cold rolled into a sharp crescent diamond shaped cross section having a tensile strength in excess of 200,000 psi and a smooth surface of 8 to 16 micro inches.

HELI-COIL TAPS

The taps supplied with kits and sets are referred to as STI or Screw Thread Insert taps. These taps must be used for Heli-Coil repairs. The STI taps supplied for standard thread repair look like conventional taps and may be used with the same tap handle as conventional taps.

If the extraction tool doesn't work then there is another option available. This involves using a pair of pliers to get in between the helicoil and the tapped hole. Once the helicoil is lifted or pulled out slightly, use a pair of pliers to rip the helicoil out.

Strength: A key-locking insert is much stronger than a helical insert, particularly in high temperature and high torque environments. Ease of Install: A key-locking insert is easier to install than a helical wire insert. Price: A wire insert is much less expensive than a key-locking insert.

Strength: A key-locking insert is much stronger than a helical insert, particularly in high temperature/torque environments. Easy Installation: A key-locking insert is easier to install than a helical wire insert. Price: A Helical wire insert is much less expensive than a key-locking insert.

The Time Sert kit is a bit more comprehensive than the Heli-Coil. It comes with the Time Sert itself, which is a solid piece, plus the correct drill bit, a countersink, a threader and the insertion tool. Just like with the Heli Coil, you'll start by using the drill bit provided in the kit to get the hole drilled out.

Why are Helicoils Used? Helicoils allow for screws to be inserted and removed without damaging the native threads on a part. Threads can get damaged over time, but helicoils can be replaced if they start to wear. Helicoils expand into the thread they are inserted into and they require a special thread to be cut.
