Don't ever use these !

I know them as Molex pins, the exact part number or nomenclature is unknown to me.  Hopefully they've died out completely but in the mid 1970s they were a cheap way to socket IC chips.  As can be seen they are essentially the metal part of an IC socket but without any plastic or fiberglass for insulation.  They are on .1 inch centers, the same as a DIP IC.  Solder them into one side of the holes for a DIP chip and then the metal tab can be broken off with a little back and forth wiggling with a needle nose.  The problem is that since there isn't any insulation it's easy to short pins together accidentally.  Also they can easily be bent out of alignment.  Finally they don't hold the IC that tightly.

I first/last used them in the Accu-Keyer by WB4VVF.  Why I chose them instead of sockets I don't know, probably just cheaped out.  Anyway, as can be seen here I ended up having a lot of trouble with them and replaced almost all of them with either pin sockets or IC sockets.

BTW, here is a page of comments from WB4VVF that came with his board:

My favorite comment is:  

"Some of the IC sellers who advertise in the ham magazines must procure their parts at night with brooms."  

Might well be applied to some ebay vendors today.  Fake ICs are not a new thing.

Possibly WB4VVF is why I used both Molex pins AND a Brown Brothers paddle ?  The paddle was a good buy, one out of two recommendations isn't bad :)

Finally, this is a neat page on the Accu-Keyer by K7MEM:
