All commercially-available In Die Tapping (IDT) designs today utilize some sort of spring-loaded misfeed protection system which is intended to protect the tap and, most importantly, the tapping device itself in the event of a:

* No-hole condition due to a short feed of the material strip
* No-hole condition due to a broken or missing pierce punch
* Undersized hole condition due to a broken or missing extrusion punch

Although misfeed protection systems are included in commercial IDT designs as fail-safe, protective mechanisms - It's still very wise for the end user to employ some method of ensuring a pre-tapped hole is successfully produced on each and every press cycle and precisely fed into position to be tapped.

Locating and Fixturing Pins
Locating and fixturing pins are press-fit, removable hardware devices designed to align or affix two work pieces to very small tolerances. When translation mechanisms are not stable or precise enough to place objects in position for a particular process, locating and fixturing pins can ensure an accurate alignment.
