Lutz (and all).
I really, really recommend getting the Lesker catalog and reading each page multiple times. I'm not saying buy from them -- they are a convenience store with prices to match. But the tech info on what's available, how well each thing works and so forth will save more money than buying some odd thing from them will ever waste -- and sometimes that's way worth it to save the time over homebrew (even for me, with a shop that can make most things). I do like the above suggestions of plastic "gasket" and shoulder washers so you can still use steel bolts, though -- sweet idea.
The online Lesker and the printed catalog are two different animals -- request and get the true laptop version! It is the very cheapest and also the best education in high vacuum technique you can get.
They want this stuff to work for you, so they get to keep the money, and they try pretty darn hard.
Nothing they say in there...has been wrong for me so far, and I've tested all their assertations insofar as possible here. Very dense info in their "tech tips", no BS, just the straight factual operational experience talking there. You could spend a few hundred bucks on books and not get as much good and true info.
