HELICOIL® is the preferred choice of many leading engineers worldwide who need to strengthen, reinforce or repair screw threads in soft alloy components. HELICOIL® inserts ensure high-strength threads, transferring forces from flank to flank into the holding thread. This is a system of high reliability for which German and international industrial property rights have been filed and which is available worldwide. HELICOIL® provides thread inserts which are produced according to consistent material and quality specifications and its technology is the basis of many national, aeronautical and military standards. Many leading large-scale users base their manufacturing standards on this system.

Structural components: Wherever low-strength materials (e.g. aluminium, magnesium alloys and fibre-reinforced plastics) are used, HELICOIL® is said to be indispensable for thread reinforcement. This applies particularly to aerospace applications, mechanical and plant engineering, the automotive industry and electrical and medical engineering. Thread reinforcement prevents wear of the threaded hole - even after frequent use. HELICOIL® also allows miniaturisation and lightweight construction in the development of series production parts. The required strength is ensured by using thread reinforcement with HELICOIL®.

The precision and reliability of the HELICOIL® wire thread inserts have been well proven by the demands of the aerospace and defence industries over the decades and are used extensively in some of the world’s most popular and modern airliners. The product portfolio includes a wide variety of globally referenced aerospace and defence specification wire thread inserts specified and used by major manufacturers around the world.

The list of certified approvals for HELICOIL is comprehensive and includes such standards as AGS3600, AGS370, AGS4677, EN2942, EN2944, EN3542, MA3281 , MA332. A typical example of the use of HELICOIL would be in the design of aircraft seats made of high-strength aluminium with an anodised surface finish.

From a practical viewpoint, installing a HELICOIL 6-32UNCX x 1.5d Screw-Lock type permits frequent assembly, disassembly and re-assembly without the risk of thread wear while also adding an in-built thread locking feature for added joint security. Parts are manufactured in accordance with LN-9499
