ABSTRACT:
A nut and a screw bolt form a screw connector, wherein the nut is secured to the bolt by a configured spring locking member. The locking member engages with one end the screw bolt and with the other end the nut, whereby the locking member has such a configuration that one end has a projection to engage a cotter pin hole in the bolt, while the other end engages directly or indirectly the nut. The two locking member ends are interconnected by a spring section which has such a configuration that a nut tightening torque moment is exerted on the nut when the locking member is in place. Further, the locking member is so configured that it exerts an axial compression force when its ends engage the bolt and the nut. This construction minimizes any reduction in the force exerted by the screw connector on the interconnected structural components. Additionally, any torque moment tending to loosen the nut is counteracted or prevented so that the screw connector is secured against loosening, against turning the nut in a loosening direction and losing the nut is also prevented.
