content: Hey guys,I'm trying to find out the details of this screw that came out of a Logitech Z-5450 speaker. I've been to a couple of stores (bunnings & other tool stores) but they weren't sure :\.details are, (NOTE: the screw in the diagram with the measurements is a different screw. Im just using it as reference.)So far, I think i've only narrowed it down to a 'Pan Head' screw with a Phillips head slot in the top.I'm not exactly sure how to find out the specs of the threads though :\. If anyone could post some tips or info, that would be super
