Have a look here:

and maybe here:

Olin, you may want to consider altering your hole sizes on the next PCB
revision
to accept the larger ZIF pin size.

I have used at least five different brands of ZIF sockets and of these only
the ARIES brand had the thin pins. All other brands use the wide pins.

Some of these other brands of ZIF socket are not only much easier to
operate than
the ARIES ZIF, they also can be very much less expensive and easier to get
in some parts of the world.
