How to mount circuit boards?

CrossRoads:
Are these too big for in-board sockets for your component so it can sit on the board as if soldered in?

It matches 68 pages of items, I think you mean the pin receptacles that are the first match. The smaller size is still bigger than my drill hole and probably too big to get a friction hold on my component, and at 25 cents each in quantity, for the number of holes involved, it will double the price of my project.

I'm thinking of using standoffs like http://www.dipmicro.com/store/SPC-M307B which I screw to the board before I solder the module, but if it loosened, I couldn't retighten it so maybe some threadlocker is a good idea (and I've always hated threadlocker). Also he only has 13 in stock. I already emailed him since it says restockable.
