Self-Forming Thread

These fitting use tapered-shaped and hardened threads that provide a "self tapping" action allowing them to be driven into an untapped hole. To achieve the best seal, it is better to spin the fitting into the hole. Self-Forming fittings may be replaced by any standard threaded fitting, or by another Self-Forming fitting.
