I'm looking for a draftsman/machinist reference tablet about hardware fastener dimensions. Know where to look?

Right now I'm designing a replacement metal housing for our communications and antenna module that bolts atop a transportation vehicle and need that useful information about sheet metal working, drill sizes for screws and bolts, countersink dimensions, thread pitches etc.

I've asked several associates and they all want a copy if I find it. Two gave me a copy of the same book which doesn't really fit the description.
