Bib taps
The type used for a garden or garage water supply is usually fitted into a screwed wall plate socket. To ensure a watertight fit with a threaded joint of this kind, bind PTFE plastic thread sealing tape round the threaded tail of the tap before screwing into the socket. If, when screwed home, the tap is not upright unscrew and slip one or more metal washers over the tail you will achieve an upright fit by trial and error.
