| Heli-Coil inserts are available mounted on plastic strips and wound onto reels (500 or 1000 inserts per reel). With power installation tooling, use of strip feed inserts will substantially increase installation rates by minimizing handling. |
| Universal Acceptance |
| Heli-Coil Standard and Screw-lock Inserts are the original – and have an extensive background of tension, torque, shear, vibration and fatigue tests conducted by American industry’s leading companies as well as the U.S. Military. Successful applications in the fields of aviation, electronics, industrial, automotive and military equipment provide a wealth of experience and confidence in the performance and reliability of Heli-Coil inserts. |

Helicoil Tangless Inserts
Emhart Heli-Coil® Tangless Inserts eliminate tang break-off and retrieval and are easily adjusted or removed after installation. The Bi-Directional Design installs quickly and easily from either end of the insert. HELI-COIL Tangless inserts have a bi-directional design allowing the insert to be installed from either end Tangless inserts are available as free running & screw locking Types, with all regular coatings.
Heli-Coil Tangless screw lock inserts provide a positive, self-locking torque and comply with both MIL-I-8846 /NASM8846 and NAS1130 requirements.
Typical Tangless NAS1130 Parts can be identified as in the product linecard available at this site.
Helicoil Thread Repair Kit - Professional
All HeliCoil Thread Repair Kits including the Professional Thread Repair Kits are used for creating stronger internal threads in all metals, composites, polymers and other materials by repairing damaged or stripped internal threads and regaining the original thread size. HeliCoil Thread Repair Kit creates longer lasting durable threads, avoids thread over-sizing, increases the possibility of higher torque application in weaker metals, significantly reduces the bolt breaking problems & HeliCoil being made of stainless steel protects against atmospheric corrosion. HeliCoil Professional Thread Repair Kits include everything required to do the job right – good number of inserts each of 3 lengths (short, medium & long) for multiple applications, HSS drill bit ,Finishing tap, installation tool and tang breaking tool – all in a rugged new box. These kits are available in metric range from M2 to M12 and in UNC/UNF range "4-40 to 1/2”.

Helicoil Thread Repair System
Helicoil thread repair system a reliable technology
HeliCoil System for Thread Repair & Preventive Maintenance of plastic moulds , machinery , soft metal assembly and all electro-mechanical equipment.
The HeliCoil System is for creation of Stronger & Longer lasting threads while Designing a component or Repairing of component having damaged female threads.
WHY USE HeliCoil
• Create Stronger and longer lasting threads in soft & light metal components made of Aluminium , Composite Alloys or Plastics & Polymers where internal threads of a component are prone to damage due to operating conditions of the equipment the same are fitted in.
• HeliCoil inserts are made from 18-8 grade cold rolled stainless steel having tensile strength ranging from 1,50,000 – 2,00,000 PSI , Hardness between 43-50 HRC which gives a better description of how HeliCoil inserts can withstand a good amount of assembly stress besides creating a stronger thread in weak materials.
• HeliCoil in stainless steel can be safely used in continuous operating temperatures up to 315 degree C & occasional peak temperature of
425 degree C .
• HeliCoil are cold rolled formed & have a very superior surface finish providing maximum surface to surface contact area , thereby greater clamping action and minimum friction between bolt & female thread flank.
• HeliCoil is Anti-Corrosive & Non- Magnetic
Made of 18-8 grade cold rolled stainless steel it provides a better resistance to corrosion under extreme atmospheric conditions and operational environments.
• HeliCoil reduces bolt failure, breaking & thread stripping
The common known causes of bolt failure and breaking or thread stripping are over torque , thread pitch angle errors , progressive pitch errors, high stress conditions & continuous vibrations.
In absence of HeliCoil , it has been observed that a bolt is subject to an average tightening load of more than 70% over the first two threads near to its collar or over a few threads finding a proper surface contact .
The conditions even get worst when normal machined threads are associated with threads having pitch errors and above adverse conditions.
HeliCoil stretches itself to compensate for pitch angle errors & progressive pitch errors thereby providing a better surface contact & more even load distribution to prevent the bolt failures.
HeliCoil has a “designed-in” radial & axial elasticity.
This allows the shearing load to be transformed into favourable hoop stress or radial load towards the full length of the insert. With result the load gets more evenly transformed over the entire length of the threads of a bolt, thus bolt breaking & thread shearing is significantly reduced.
HeliCoil - A Gift to Designers
The above mentioned compensation & even load distribution features allow a superior reliability of assembly and without compromising on performance Allows the Designers to choose a bolts of lower strength , bolt of alternate metals, bolt having lesser length , creating possibility of lower torque requirements for soft metals , retaining strength of components having less wall thickness.
HeliCoil inserts are also available with a locking coil for thread locking of screws & bolts to prevent loosening due to heavy or continuous vibrations.
Unlike the other methods used for thread locking like adhesives , the locking type HeliCoil is reusable for several bolt opening & tightening cycles .
Use of HeliCoil eliminates most of the given problems as it remains in a compressed state inside the threaded hole & holds tightly to the wall despite variable heat expansion , vibrations & high impact conditions. HeliCoil doesn’t get loose by repeated tightening or opening of bolt .
The HeliCoil is installed by a tool which compresses it at first to get installed in a threaded hole after which it sits tightly against the thread flanks , the only way it can be taken out is by using a tool which reduces it in diameter during extraction.
HeliCoil Cuts on outsourcing repairs , reduces equipment down time & avoid expensive conventional methods in practice.
Helicoil is an easy to use good technology & one could do it on own
at a low cost.
