In the states we typically use screws.
i forgot mention an important thing,i am not an American,
it is not necessary to know the west or other English speakers ( more accents more dialects,more confusions )
if i speak in Tamil in my native accent,
it will take decades for you to understand,
speak in a understandable way.
i hope you criticised me.
please speak to the topic,
i feel sorry to inform this ( Indian English is based on UK, for your knowledge )
