The aim of this study is to look for the suitable parameters of screw, which can make this technology attractive to the people. With this objective, the study of existing Bangladeshi screw and a few newly designed screws has been done. Four different types of new screw have been constructed, the design and idea of which are taken from the experience of the Institute of Energy in Vietnam. The remarkable features of the screw are that it is short in length and the thread is not made as an integral part of the base of screw.
