The present invention relates to a bone implant device, comprising a body having a first part and an opposite second part, the first part and an opposite second part defining a longitudinal axis, the first part including an external thread extending from a cylindrical part to the distal end of the body, the external thread comprising a first thread part having a first radius measured from the longitudinal axis and a second thread part having a second radius measured from the longitudinal axis. The first radius is larger than the second radius, the first thread part is a cutting part, and the second thread part is a contact surface. The first part may include one or more cavities for storing bone fragments while the bone implant is in use.
