If you look around, almost every big and small object around us is held together with screws, nuts and bolts. From a smartphone, to doors and windows, to cars and ships, how much ever compact or gigantic they are, they all need a fastner to hold them together.
These nuts and bolts are made from what’s called steel wire rods. After spending hours in a furnace to soften it enough to be worked, the wire rods go in a bath of sulphuric acid to remove any rust particles on it, which is then followed by various other procedures to mould it into the desired form.
Watch the video below to see the entire process of manufacturing these fastners.
