1084-10EN200 by HELI-COIL

The Heli-Coil® 1084-10EN200 is a tangless, free-running wire thread insert precision-manufactured from Inconel X-750 with a dry film lubricant coating. Engineered to create permanent, high-strength 5/8-11 UNC threads in extreme high-temperature and harsh operating environments, its tangless design completely eliminates tang break-off and removal steps, streamlining assembly and preventing foreign object debris (FOD). The precision-wound helical coil structure distributes tensile loads evenly across the engaged threads, protecting soft parent materials against stripping, thermal seizing, and wear.

Tangless Wire Construction eliminates the need for tang break-off and retrieval, shortening assembly cycles and preventing foreign object debris (FOD) hazards.

Inconel X-750 Superalloy provides exceptional thermal stability, extreme heat resistance, and high tensile strength in demanding environments.

Dry Film Lubricant Coating reduces installation torque, prevents thread galling, and ensures smooth fastener engagement under high operational temperatures.

Free-Running Thread Profile allows standard male fasteners to pass through smoothly without applying friction locking torque.

5/8-11 UNC Coarse Threading reinforces soft metals while delivering long-lasting internal thread strength under heavy structural loads.
