Genny,
I forgot  to tell that Nylon connectors are the most sold of all connectors. 
Millions and millions of frigs, toasters, rasors, food processors, anything 
for the kitchen or the office etc Nylon in all shapes...but not usable for 
anything outside the kitchen or office. Are often soldered separately after 
the wave soldering. As responsible for all our MIL connectors a couple of 
years, no Nylon could slip in, but with that said I don't miscredit Nylon 
connectors. They are  without competition seen from a price viewpoint...
