HELICOIL® Smart The new generation of thread technology for high-strength joints

We continue to make product history.

HELICOIL® Smart – The next development stage of the HELICOIL® thread technology The new HELICOIL® Smart is a further quantum leap in the HELICOIL® thread technology. A coil thread insert with tang which does not have to be broken off. The innovation: The installation mandrel bends it backward during spinning off and then compresses it. This “smart” thread insert merges the advantages of the HELICOIL® Plus and the HELICOIL® Tan

At a glance:SMART ■ Provided with a tang, but yet no tang ■ No tang break - no tang removal ■ No risks from tangs left in component EFFICIENT ■ Assembly times reduced by approx. 20 % ■ Simplified quality assurance ■ Permits blind holes of minimum depth - ideal for pre-assembled subassemblies etc. ■ One installation mandrel with two functions - 2 in 1 ■ Fastener and installation tool from a single source ■ The installation of the HELICOIL® Smart is fully automatable Identical specifications for HELICOIL® Smart holding threads as for the other HELICOIL® systems ■ Positioning and screwing in like...

Can you imagine a world without screws? Even today, the screw is the most widely used fastening element for detachable joints. Optimised tightening methods and high-strength screws allow constant improvement. Considerably higher forces can be transmitted so that the dimension or total number of required screws can be reduced. However, only highly sustainable nut threads permit high-strength screw joints. This is where our HELICOIL® thread technology is used. ■ Increased quality and value ■ Wear-resistant, low and constant thread friction ■ Corrosion and temperature resistant ■ Screw loss protection...

This smart thread insert merges the advantages of the HELICOIL® Plus and the HELICOIL® Tangfree. The HELICOIL® Smart thread insert, which is made from a wire with rhombic profile, is also formed into an elastic spiral. As to the Free Running version, thread by thread it is a completely...

HELICOIL® Smart thread inserts – a close look at the advantages Wear resistance HELICOIL® Smart thread inserts are made of austenitic chrome-nickel steel (minimum tensile strength 1,400 N/mm²). The high surface quality of the rolled thread ensures a high-strength, wear-resistant thread with an extremely small and constant thread friction torque. Therefore, a higher, constant preload-force is achieved for repeated cycles at the same tightening torque. The utilisation of the yield point of high-strength screws is improved. Torsion stress is considerably reduced. Compared to tapped threads, the...

Tight fit When not installed, the outside diameter of the HELICOIL® Smart exceeds the receiving thread by a defined amount. In combination with the high spring force of the material, this difference in dimension results in radial expansion and therefore in the tight and clearance-free fit in the nut thread. Additional locking elements or adhesive – as are common for fixed bushes – are therefore obsolete. If you use impact wrenches, please contact us. We will be happy to help you. Friction Thread friction and its scatter range can be reduced if a HELICOIL® is used. The dispersion range can be...

HELICOIL® Smart application areas HELICOIL® Smart thread inserts create high-strength, stable joints in low-strength metal materials (lightweight design) to be used in diverse industries, such as: Mechanical and plant engineering Electrical industry Automotive engineering and vehicle manufacturing Tool design and construction Telecommunication Agricultural machinery

HELICOIL® thread technology: variants HELICOIL® Smart Free Running The new thread insert merges the advantages of the HELICOIL® Plus and the HELICOIL® Tangfree. Every thread of the thread insert with precision-formed, rhombic profile is free running. The result is a true-to-gauge internal thread including the last thread which is in every case threadable. Just like the HELICOIL® Plus, the HELICOIL® Smart is provided with a special thread start to allow easier installation in a holding thread. There is a tang, but it does not have to be broken off and removed. The installation time is therefore...

HELICOIL® Plus Screwlock This thread insert has an additional screw-loss protection area. One or several polygonal-shaped threads clamp the flanks of the installed screw. The elastically resilient frictional locking results in prevailing torques similar to the specifications of ISO 2320. These screw locking torques meet the demands of technical delivery terms regarding international standard specifications. However, the prevailing torques can also be adjusted as required for the corresponding application, e.g. for securing of setting screws. HELICOIL® Plus Screwlock can only be used with screws...

HELICOIL® Smart installation HELICOIL® Smart thread inserts can be easily and economically installed because there are only a few basic rules to observe. There is a broad range of installation tools for efficient installation – for individual applications as well as for large-scale production. Installation phases are as follows: Drilling Common twist drills are used. Notes on diameter and tapped hole depth are given on page 19. Prior to tapping, counter-bore 90° and deburr. Outside diameter of countersink = DHC + 0.1 mm. On the cut holding thread, the countersink is hardly visible. Tapping To...
