  · This hollow pin contributes to weight reduction when compared with solid pins.
  · Used for positioning, turn prevention, and retention, etc.
  · Used for simple fastening and positioning, etc.
  · Its grip prevents it from dropping out from its mating hole.
  · When it is necessary to increase the shear load, use a double-pin structure. (The load is made by adding the shear load on the outer and inner pins.)
