  • Threaded fastener
    Patent number: 3972361
    Abstract: A vibration resistant fastener such as a screw or bolt provided with a series of serrations on the load bearing flank of the thread of a screw or bolt so that the serrations will bear on the pressure flank of a mating thread. Each serration is formed with an inclined ramp terminating in a substantially vertical buttress with the smoothly inclined surface of the ramp being oriented in the direction of tightening so that the buttress presents a surface tending to act against rotation of the fastener to preclude loosening of the screw or bolt.
