To echo the over comments, a good if difficult fit. Unfortunately I didn't have a socket bigger than 30mm so I just used the biggest punch I had. It didn't take massive amounts of effort to fit.
You won't get these to fit by hand, but I expect most people have a tool that can be manipulated in the right fashion. Just don't use anything sharp!
