The video shows a man's arm and hand as he uses a wrench to turn a bolt on a piece of machinery. The man's arm is hairy, and the machinery appears to be made of metal. The bolt is silver and has a hexagonal shape. The man's hand is wearing a black glove, and he is using the wrench to turn the bolt clockwise. The background is dark and blurry, but it seems to be a workshop or garage setting.
