Hi,
Here are two different ZIF sockets.
Notice a machine-tooled socket near the ZIF socket within the two certain pictures. Observe the ZIF socket's size to the machine-tooled socket's size.
You can put an Aries ZIF socket on a machine-tooled socket with very little effort. You won't be able to put a 3M ZIF socket on a machine-tooled socket and will be frustrated.
There are two sizes of Aries ZIF sockets. One is big. The other is low-profile.
I hope this post helps reduce curiosity.
Regards,
