I like the screws holding down the socket.

It is indeed an interesting thread, however in my case I just felt that 
there
was not enough contact at all and also this particular 
implementation was done
on the cheap, rather badly. In fact there was 
about 5 fingers at each of the
fixing positions for the socket, many of 
which had broken off. I felt that
this was not an ideal situation and so 
decided to remedy it. I mistakenly
thought that the SK-1900 was in fact 
a socket with a grid collet but have
since found out that this is not 
the case.

A picture speaks a thousand
words so have a look at
this:

Notice
the sputter marks, apparently the blower failed and no one
noticed!
