Notable Features: 
  • The largest diameter at .040" diameter (1 mm)
  • Middle diameter at .029" diameter (.74mm)
  • Small diameter at .019" diameter (.48 mm)
  • The glass sealing area of the pin is the .029" diameter-allowing for a robust platform that will not move (& crack the glass) on which the .019" dia. Lead can be bent. Also the .040" headed portion creates a large target for wire bonding or brazing.
  • Production is faster than machining or grinding.
  • Very little waste; scrapless.
  • Excellent surface finishes are attainable without the possibility of machining lines around the outside diameters.
  • Cold forming process does not risk the usual machining tit issue at the end surfaces.
