	Are the values OK? it seems more like an worm rather than a screw (Pitch is more than half bolt diemeter) The calculation of stretch at thia pitch will be a bit complicated since the stretch as per hookes law , will be dependent on Young's Modulus and then the effective crossectional area (and also the material and properties of the female threaded portion).
