UNIT 4 TRANSMISSION MACHINES

I thought that it was interesting to have more information about nut and bolts because we think that transmission machines are made to use it but before and first of all you have to manufacture them with other machines and workers.So,here is a video of the manufacturing process of nut and bolts of Discovery Channel.
I hope you will like it and found it interesting.
