You must choose an option from above before adding to your cart.

Let imaginations run wild as students construct massive cardboard bridges, buildings, or forts using this durable polypropylene hardware building set. Students develop engineering and architecture skills in three-dimensional spaces as they solve problems and discover the strongest connection points for larger constructions. Unique channel and tab design allows students to press nuts on quickly and twist to lock in place for more efficient building. Press the nut and bolt together tightly for a fixed connection between panels, or create a pivoting joint by leaving space for panels to slide past one another.

Choose sets in various quantities, with or without cardboard and hole punches. Recommended for Lower Elementary and up.
