(22) of the nut (10) is a usual bore for receiving the shank of the screw (16) matching to this nut (10) while the workpiece (14) facing the enlarged section (22) of the nut (10) is having a bore with an interior diameter which is corresponding to the exterior diameter of the non-enlarged section of the rubber or plastic member (24) in the non screwed-up state such that in the screwed-up state of the connection the workpiece (12) onthe side of the screw head in the usual way is held between the nut (10) and the screw head of the corresponding screw (16) while the workpiece (14) facing the enlarged section (22) of the nut (10) is contacting the enlarged section (26) of the rubber or plastic member while it is held in the other direction by the enlargement of this member (24) caused by the compression of the rubber or plastic member projecting beyond the nut (10). Connection according to claim 1, characterized in that the exterior diameter of the enlarged section (26) of the rubber or plastic member (24) is larger than or equal to the exterior diameter of the enlarged section (22) of the nut body (18). Connection according to claim 1 or 2, characterized in that the non enlarged section of the rubber of plastic member (24) is provided with lips (28) on its generated surface by the means of which the nut (10) is fixedly held in the workpiece (14) facing the enlarged section (22) of the nut (10). | Acument GmbH & Co.

In one embodiment, a method for mitigating electrical surface discharges from a CFRP component includes first applying an insulating primer to a metallic component. Next, an insulating primer is applied discontinuously to the CFRP component adjacent the metallic component. The discontinuous application of the insulating primer forms a primed portions and unprimed portions. The unprimed portions are configured to enable electrostatic dissipation. | 1. A method to mitigate electrical surface discharges, comprising: applying a first insulating primer to a metallic component;providing one or more electrostatically dissipative features to a carbon fiber reinforced plastic (CFRP) component adjacent the metallic component; andapplying a second insulating primer discontinuously to the CFRP component to form at least one primed portion and at least one unprimed portion, the at least one primed portion being disposed adjacent the electrostatically dissipative features,wherein the insulating primer comprises a corrosion resistant finish to at least prevent galvanic corrosion of the metallic component; andwherein applying a second insulating primer discontinuously includes forming the at least one primed portion so that it extends at least approximately 1.75 inches from the metallic component. | 1.

The method of claim 1, wherein applying a second insulating primer discontinuously includes forming the a plurality of primed portion and at least one unprimed portion such that each primed portion is separate from an adjacent primed portion by at least 0.25 inches of some unprimed portion. 4. The method of claim 1, wherein applying a second insulating primer to a metallic component includes applying an insulating primer to an aluminum component. 5. The method of claim 1, wherein providing one or more electrostatically dissipative feature includes one of a primer coated metallic component, a k-code fastener, an uncoated fastener, and an unprimed portion of a CFRP component having a minimum cross section of 0.25 inches. 6.
