helicoil无尾螺套 普通型 Free Running
You do not need a tang to install these thread inserts. Therefore, tang break and removal are not required. Combined with the matching installation tools， the current innovation status in the helicoil technology is a perfect addition to the helicoil product family. helicoil无尾螺套 锁紧型 Screwlock Helicoil Tangfree Screwlock has the same advantages as helicoil Tangfree. In addition, there is a screw-locking area. The screw is locked by one or several polygonal-shaped threads clamping the flanks of the screwed in 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. helicoil Tangfree Screwlock can only be used with screws of higher property classes (8.8 and higher). Common lubricants according to the manufacturers’ recommendations shall be used for highly alloyed screws. This thread insert is widely used in the aviation industry.
Tangfree thread insert ： 1、No tang break – no tang remova 2、No risks from tangs left in component 3、Reduced installation time due to less process steps 4、Reduced testing and documentation effort
