Although some of these specialty products are current carrying members without silver, most of them are not contacts. Mostly made from copper, they are however used as terminals; for example, as shunts in ground-fault devices.

Deringer does not normally compete with commercial cold-heading houses because our customers want tighter tolerances. Customer prints of screw machine parts are continually being evaluated to determine whether tolerances, configuration and materials will lend themselves to conversion to the more economical heading processes. Also, in many cases our modern punch press department performs secondary operations on such headed parts-and all done at lower cost than by any other means.
