FEMA is responding to severe storms and flooding that damaged or destroyed thousands of homes across Tennessee in May 2010. David Fine/FEMA
context_page_description: A drawing pin or thumb tack is a short nail or pin used to fasten items to a wall or board for display and intended to be inserted by hand, usually using the thumb. A variety of names are used to refer to different designs intended for various purposes.
  Thumb tacks made of brass, tin or iron may be referred to as brass tacks, brass pins, tin tacks or iron tacks, respectively.
  These terms are particularly used in the idiomatic expression to come down to brass tacks, meaning to consider basic facts of a situation.
context_section_description: A drawing pin has two basic components: the head, often made of plastic, metal or  wood, and the body, usually made of steel or brass. The head is wide to distribute the force of pushing the pin in, allowing only the hands to be used. Many head designs exist: flat, domed, spherical, cylindrical and a variety of novelty heads such as hearts or stars. Drawing pin heads also come in a variety of colours. These can be particularly useful to mark different locations on a map. Some drawing pin designs have a portion cut out of the head and bent downward to produce a pin.
  Domed or gripped heads are sometimes preferred over flat heads as dropped flat-headed pins may easily point upward, posing a hazard.
  Drawing pins also pose a hazard of ingestion and choking, where they may do serious harm.
