| (documentation Bolt EnglishLanguage "Any AttachingDevice that is designed to mate with a MechanicalNut thereby Attaching two Objects. This includes nuts with hexagonal heads that must be held or turned by a Wrench or Screwdriver as well as those that have round heads but some non_round feature that is designed to catch on the material being attached, and therefore prevent rotation, as in a carriage bolt. Bolts are distinguished from Screws in that screws must create a mating surface by gouging a thread into material, whereas bolts are designed to slip through a hole and are held in place by a nut at the opposite end from the head of the bolt. This includes threaded rods that may have nuts as spacers for freely rotating items.") | Cars.kif 4223-4231 | |
