In the video, a person is seen holding a small object in their hand. The object appears to be a small metal piece with a hole in the center. The person then proceeds to insert the object into a hole on a larger metal piece. The larger metal piece has a bolt and nut on it, and the person uses their fingers to turn the bolt. The person's hand is visible throughout the video, and they are wearing a black wristband. The background is not clearly visible, but it seems to be an indoor setting with a wooden floor.
