Whoever says "Tempo" means handkerchiefs and whoever says "Helicoil" means thread repair - HELICOIL thread inserts have proven themselves in practice for 65 years!
The well-known thread inserts create stable connections in soft metallic materials such as aluminium and save many an internal thread - no matter whether simple M8 threads for holders of all kinds or even for spark plug sockets that have been screwed through.
They are available in Free Running and Screwlock versions. The green or red colour facilitates identification when installed. You can get the complete Helicoil range from us. In addition to the individual taps and drills, you can also get the complete kits and the matching refill packs.
Anyone who has used Helicoil to repair a worn-out internal thread on a gearbox or engine block will appreciate the ease of use and, above all, the durability of the internal threads produced. Helicoil is simply unbeatable - both for private use and for companies and screwdriving professionals.
