When I remodeled my kitchen, I found some
pulls I liked a lot at outwater.com. (See my earlier
thread for pics on the remodel job.)
Unfortunately the pulls are European and the screws are metric. They had the breakaway sections on the screw, but the screw length I needed was between breakaway sections. Ever tried to buy a metric screw cutter? I spent a day going to every hardware/electrical supply store in a 15 mile radius with an astounding lack of success.
I spent another two days googling for a 4MM screw cutter. Googling “metric screw cutter” did not yield any usable results. I (finally) tried googling “electrical tools” and found the doodad I needed at
http://www.mcmaster.com/ , page 720. Here’s what those lovely folks sent me:

The moral of the story is: don’t buy hardware that uses metric screws unless you have or have found a metric screw cutter.
FWIW, outwater.com has a
very large selection of 'stuff' for most projects.
