Original HeliCoil Plus taps are adapted for this thread system and must be used for tapping the threads. HeliCoil Plus taps can be used to create threads in Aluminum, Magnesium, Steel, Copper, Bronze, Brass and Zinc alloys. In addition, HeliCoil Plus internal thread limit gauges must be used for checking that the thread is true to gauge. Also known as Pre-cutter taps, roughing taps are used to create the initial threads.
