The thread insert is a wire with rhombic profile formed into an elastic spiral. It is positioned and screwed in like a screw. To screw in the thread insert, all you need is an installation mandrel with thread dimensions similar to a tap of the same nominal diameter. However, existing tools of the commonly used design can still be used for installation. Thanks to the considerably wider range of tools to be used for installation, installation times are up to 20 % shorter than for previous methods. If through-hole threads are required, after installation, the tang can be broken off at the notch (predetermined breaking point). HELICOIL Plus produces high-strength threads transferring forces from flank to flank into the holding thread. It is a highly reliable system for which German and international industrial property rights have been filed. HELICOIL Plus are thread inserts produced according to consistent material and quality specifications and meet the requirements of national standardisation as well as aeronautical and military standards. Apart from that, leading large-scale users base their manufacturing standards on this system. 2
HELICOIL Thread inserts Your advantages – an overview n High thread loading n Increased quality and value n Wear-resistant, low and constant thread friction n Strong n Corrosion and temperature resistant n Cost-effective n Tight fit Defective thread Repaired thread Strength The elastic properties of the HELICOIL thread insert allow a uniform load and stress distribution. An optimum flank contact is achieved. Variable pitches and angles are compensated for over the entire length of the thread insert. Force transmission from bolt to nut thread is optimised. The quality of the screw joint is considerably increased – for static as well as dynamic operating loads. Due to the improved distribution of the preload force, the fatigue strength of dynamically loaded screws is increased. This is why the HELICOIL is also suitable for use in threads in high-strength materials, e.g. steel or cast iron alloys. Process n HELICOIL Plus thread inserts are screwed in just like a common screw. The tool sleeve with leader catridge, that was required in the past, is no longer needed. All that is needed for screwing in is an installation mandrel the size of a screw tap. n The mandrel can be compared to a screw tap energised by a die wrench or other common tools from nut bodies with ratchet wrench. For particularly low-height thread repairs, the mandrel can be extended. The HELICOIL Plus thread insert is screwed in until the nose meets the tang. Therefore, the thread also works in vertical installations. It guarantees safe repairing of threads. n To determine the right depth of insertion, the last spiral wire has to be situated under the first flank of the thread. n Since HELICOIL Plus threads are installed without a leader cartridge, the depth of insertion can be visually checked. Thus, it is not necessary to use a depth control stop as it is for tools using leader cartridges. For easier identification in the fitted position, HELICOIL Plus threads are green-coloured. n After installation, the tang is broken off at the notch (pre-set break-off point). n The new HELICOIL Plus technology allows repairing threads, that up until now could only be repaired using special tools. 3

HELICOIL Practical examples for thread repair Repairing of damaged spark plug threads In the automotive industry, the HELICOIL Plus thread technology is widely used to provide high strength threads. Thanks to efficient repair of damaged threads, valuable components do not have to be replaced. Thread repair for aluminium engines With HELICOIL Plus thread inserts, cost-intensive replacements of threads in aluminium engines, such as employed in motor sports, are no longer necessary. Preventive installation of HELICOIL Plus ensures minimum effort for thread repair during engine life. Thread repair in different industry sectors Common applications relying on threads are employed in the machine and plant construction, power plant engineering and shipbuilding. Scrap reclamation: high volume production parts with damaged threads can be reworked. Thread repair involves multiple standards. HELICOIL Plus thread inserts comply with certifications for numerous industries, e. g. approved by: n Technical Inspection Authority (TÜV) n Germanischer Lloyd n DET Norske Veritas In the field of nuclear energy, an individual inspection is being conducted. 5

Falling short of recommended nominal lengths is acceptable if proven by testing. Intermediate lengths are also available. Temperature limits for validity: aluminium alloys Tmax 300 C, magnesium alloys Tmax 100 C. For the design of screw joints under thermal stress, the changes of temperature-dependent material parameters must be taken into account. * Minimum wall thickness (related to outside diameter of the HELICOIL receiving thread) * Assessment of the minimum wall thickness is mainly predetermined by the individual operation data. The operation data in turn determine the strength of the material and the length of the thread. The quoted guideline value formula applies to aluminium, cast and wrought alloys and a HELICOIL screw-in thread length of 1.5 d. d Nominal diameter of the holding thread DHC Outside a Remaining wall thickness * For grey cast iron on request.
