Bolt spanner is a useful material for developing eye-hand coordination and fine motor skills. It consists of a wooden board containing a keyway and four cavities in which the hexagonal bolts to be locked can be inserted. The bolts can be removed from their holes and placed in the circular cavity in the board. The game is useful for the development of eye-hand coordination and fine motor skills, and meets the child's need for self-reliance and independence.
