Patent attributes
A structural screw device for a radiator assembly includes a frame and four screw members. The frame with four corners provides at least a leg post with an axial through hole respectively. The respective screw member is inserted into the leg post and the main body of the screw member is surrounded with an elastic member. The axial through hole of the leg post provides a step at intersection of the first and second hole sections. The free end of the leg post has split paw portions and each of the paw portions has an inner projection such that the neck section is caught with the projection while the screw member is inserted into the through hole in a way of the engaging section extending to the paw portions and the elastic member being biased against the step. Therefore, the projection is capable of being propped up to be away from the neck section and restoring to hold the neck section.
