Thread insert HELICOIL® tangfree

Installed quickly and securely – and no tang to break. The innovative coil of the insert allows installation from both ends with identical quality. Thanks to the reduced thread on both ends and the coil ends optimised for insertion, the HELICOIL® Tangfree thread insert can be installed without special alignment. The HELICOIL® Tangfree is easily screwed onto the mandrel and goes into the pilot thread smoothly. The spring-mounted installation blade grips into the notch of the coil thread insert and securely installs it in the prepared pilot thread. In addition, the optimised geometry minimises wear on the tools. The tool concept is impressive, boasting long service life for the blades and simple maintenance.
