Many types of fasteners require selective heat-treating for the applications they will be used in. Due to the liability of these applications, complete quality control is necessary for each fastener, which requires sophisticated monitoring and accept/reject capabilities. Pillar has addressed these sensitive issues with each system it has built, and tailored it to the requirements of the customer and applicable industry standard.

• With the selection of the proper power level, frequency, and inductor design, our automated system can be used for hardening specific bolt threads to a particular case depth. The bowl feeder, rotary dial process fixture, and exit accept/reject mechanism make this a complete automated machine needing only occasional tending.
