Bolt or Bolts.
Are iron pinnes belonging both to the building, and rigging of a Ship; of which there are divers kinds, as Ring-bolts, which are of infinite necessary use, both for the bringing to of the planckes and wales to the ship, as also the chiefe things whereunto we fasten the tac∣kles and breetchings of the great Ordnance. Drive-bolts, which is a long one to drive out an other bolt, or Treenell by. Set-bolts, used in the buil∣ding, for fireing the planckes, and other works close together. Ragg-bolts, which are sharpned at one end and jagged, that they may not be drawn-out. Clench-bolts, which are clinched with a Riviting hammer, to prevent drawing out. Fore lock-bolts, which are made at the end with an eye, whereunto a fore-lock of iron is driven over a Ring, to keep it fast from starting-back. Fender-bolts, which are made with a long head and beate into the outward most bend of the Ship, to save the ship sides, if an other ship should lye a-boord her. Bolts are many times cal∣led according to the places whereunto they are used, as chaine-bolts, bolts for Carriages and the like: The use of them is so great, that without them a ship cannot be built strong, for they bind together all the timbers knees and the like, which doe strengthen the Ship.
