Since the Moon's orbit centers on the Earth, rather than the Sun, it would be a little confusing to think of the Moon's orbit as a year. Instead, this cycle of the Moon orbiting the Earth is much closer to our calendar system of months. It takes 27.322 days (or 655.728 hours) for the Moon to orbit the Earth. If that number looks familiar, it's because the orbital period of the Moon is exactly the same as its rotational period.
A self-sealing stem bolt. Self-sealing stem bolts are a basic component of reverse-ratcheting routing planers. (DS9 episodes: Progress, Prophet Motive) They consist of 80% mixed duranium, aluminum, and steel alloys, 11% electrically modulated ceramic, and 9% thermally stabilized plastic.
A bolt is an externally threaded fastener designed for insertion through holes in assembled parts, and is normally intended to be tightened or released by torquing a nut. A screw is an externally threaded fastener capable of being inserted into holes in assembled parts, or mating with a preformed internal thread or forming its own thread, and of being tightened or released by torquing the head.
