Does this mean that fitting nails can be used as regular pins? So a 6 pin connector such as Molex 505066-0622 has in fact 8 pins? Also as the contact resistance of the fitting nails is lower, they are even better suited for transmitting power?
Molex Glossary Terms state:
Fitting Nails: Connector component that increases the mechanical retention of the component to the PCB by increasing solder area. Fitting nails relieve stress on solder joints.
The primary purpose of fitting nails is to keep connector on SMD PCB, but are speced for 50V AC or DC at 3A. Therefore they can be used for power.
