Product Description
The Heli-Coil® T1185-04E224 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 #4-40 UNC threads in extreme high-temperature and harsh environmental conditions, its tangless design eliminates tang break-off and removal steps, preventing foreign object debris (FOD). The precision helical coil structure delivers exceptional heat resistance and load distribution, protecting soft parent materials against thread stripping, galling, and wear under thermal stress.
Tangless Wire Construction eliminates tang removal steps, reducing installation time and preventing foreign object debris (FOD) hazards in sensitive assemblies.
Inconel X-750 Superalloy provides superior high-temperature resistance, thermal stability, and high tensile strength in critical environments.
Dry Film Lubricant Coating lowers installation torque and protects mating threads against galling, seizing, and high-temperature oxidation.
Free-Running Thread Profile allows standard male fasteners to pass through smoothly without applying locking friction.
#4-40 UNC Coarse Threading reinforces soft parent metals and repairs worn internal threads in compact, high-precision components.
