5 Reason to break off the Tang
Flight Safety/Critical Applications - a loose (FOD) tang could create a particularly hazardous, and possibly life threatening situation in airborne applications, e.g. aircraft or missiles.
Seizing, Galling, and Insert Movement - a loose tang contacted by the bolt or screw can cause metal-to-metal contact likely resulting in galling.
Full Thread Engagement - the chamfered threads of the bolt or screw must pass completely through the installed insert so that the entire length of the insert is engaged by the threads of the bolt or screw.
Added Cost - utilizing an insert that is longer than necessary increases the drilling and tapping time to accommodate the additional length. This also increases tooling costs due to wear and breakage.
Military Standard Approval - MS33537, the assembly specification for helical coil inserts states, “The tang should be removed from the insert after installation."
