Abstract
A fastener comprising a nut with V-threads modified to have a wedge ramp between adjacent flanks at the root thereof and characterized by the uniform pitch of the nut thread being a predetermined amount greater than the uniform pitch of the bolt thread which, in combination with the wedge ramp, results in optimum stress distribution within the bolt as well as a prevailing torque and anti-vibration relationship between the nut and bolt.
