Narrative:

The pilot flying and I briefed the landing. We went through the before landing checklist. He extended the landing gear. The three gear indicator lights were illuminated. The nose gear was present in the mirror on the left engine nacelle. Tower cleared us for landing and we turned to the final approach. Again; we verified the landing gear was down. We continued on a normal glide path to the runway. The aircraft touched down on the main landing gear first; followed by the nose gear. A vibration began to resonate from the nose of the aircraft. There was a 'clunk' sound and the nose fell to the ground. The aircraft skidded down the runway. We maintained directional control. Once stopped; we secured the fuel and electrical systems. Then we immediately departed the aircraft. We called the control tower from our cell phones. The aircraft was examined the following day. A bolt in the nose gear assembly had failed.
