Automotive side terminal batteries have historically used a wrought stainless steel nut that is imbedded in the lead side terminal as the means of connecting the battery cable to the automotive battery. Our talented team of designers and engineers envisioned a deep drawn nut as an alternative to the wrought nut. One of the problems with the wrought nut is if the end user decides to use their own bolt to connect the battery cable to the battery, and if that bolt is longer than the OEM bolt, the longer bolt can run straight through the bottom of a wrought nut and enter the sealed interior of the battery, possibly causing the battery to explode, with possible serious injury. This provides potential liability concerns for the battery manufacturer.

Our deep drawn battery nut was designed so that if too much torque is applied to the incorrect length bolt when connecting to the battery terminal, our battery nut will prevent the incorrect length bolt from entering the sealed battery container.

In addition to this safety design feature our drawn battery nut represented a 16% savings over the wrought nut.

In the appliance dishwasher industry, the heating element in a dishwasher is secured to the interior tub of the dishwasher by means of a bushing that is attached to the ends of the heating element. These bushings were typically a screw machine part produced from brass and to the heating element by silver solder.

Our design team devised a deep drawn bushing made from CDA 220 brass that represented a 32% cost savings on bushings to the heating element manufacturer and ultimately to the dishwasher manufacturer. Initially our deep drawn bushings were silver soldered onto the element but as time went on, we devised a practice of attaching the bushing to the heating element using epoxy.
