Did that, been there many times.
Metal oscillators as well as the plastic body Seiko's fit nicely into a machined pin type IC socket. In fact, they make IC sockets specifically for oscillators. Normal legs on one of these oscillators is 0.018 round", same -width- as a normal DIP type IC. The fact that an IC leg is normally 0.01" thick versus the 0.018" doesn't affect a machined pin socket.
The added thickness is, however, on the edge of what a stamped socket can take.
I have also seen 0.025" headers do wondrous and permanent things to IC sockets.
