This results in a continuous increase in the screw pre-load F. When the elastic limit of the screw (dependent on the material) is reached, further angular rotation requires little increase in torque, and the resulting pre-load force increases only slightly (plastic deformation). A screw should ideally be tightened to approximately 90% of its elastic limit. Elasticiimit Breaking point / / / / AM MF (joining torque) Rotation angle
