Abstracts: This project is based on the pneumatic system. The screw driver works on the principle of pneumatic system. The complete working model of screw driver is formed in this project which contains equipments like cylinder, hoses, foot air pump, pneumatic screw driver and air seals at connection. The principle of each part is described briefly in this project. This model “saves energy”. In case of electrically operated screwdriver electricity is required. In pneumatically operated screw driver air is required which is freely available in atmosphere and can be stored using foot operated pump for later.
