You can identify a galvanized screw by its distinct shiny, silver-gray appearance, which comes from the zinc coating applied to protect against corrosion. Additionally, galvanized screws often have a slightly rougher texture compared to non-galvanized screws. You can also check for markings or labels on the packaging, as manufacturers usually indicate if the screws are galvanized. Lastly, performing a simple magnet test can help, as galvanized screws are typically made of steel and will be attracted to a magnet.
A wood screw will have a courser type thread and will have a sharper point.

galvanized metal is a silvery gray colour which also has a pattern on it.
There are copper fittings that will connect to galvanized.
yes
without touching it? no what you will have to do is sand or scrape the pipe then you will be able to tell the difference. if its a dull metal then its black iron but if it shines then it would be galvanized.

Even though I am in a different country, you should use Black Iron pipe, not galvanized. The other option is copper. Check your local bylaws, GET A PERMIT! This is essential. If you screw up and do not have a permit, you will NOT be covered by insurance!
Yes.

To accurately determine the size of a screw, you can use a screw gauge or a caliper to measure the diameter and length of the screw. Match these measurements to a screw size chart to identify the correct size.
Yes. Use a threaded fitting, male or female as needed on the copper and screw the galvanized into it.You must use a dielectric fitting to connect copper to galvanized pipe. If you don't, a galvanic reaction will occur and the piping will corrode and leak. You can use a Dielectric Union or a Threaded Brass fitting to join the two types of piping together.UNIONS can leak the best answer would have been a dielectric nipple
Yes, first the Galvanized pipe has to be threaded with a standard thread for pipes, then you buy the correct female socket threaded plastic fitting, screw it onto the pipe using Thread pipe sealing tape, then glue your piping into the socket part of the plastic fitting, simple. Cheers.
Use a magnet IF it sticks its ferrous metal if it does NOT stick it is non ferous metal
