unverlierbares befestigungselement for assembly to plattenfu00f6rmiges material

摘要

A captive nut 101 is mountable on a vehicle panel 113 and has a blind bore 131 for receiving a fixing 159, such as for mounting a roof rack. The nut forms a watertight seal with the panel. The captive nut 101 comprises an outer tubular portion 125 forming a riveting skirt and an inner tubular portion 127 disposed coaxial with the outer tubular portion 125. A flange 105 extends radially from an end of the outer tubular portion and splines 109 extend radially from the outer tubular portion to the flange 105. The height h of a spline 109 in a direction perpendicular to the axis Y-Y is substantially the same as the length l of the spline in a direction parallel to the nut axis. The thickness t of a spline is half the height of the spline in a direction perpendicular to the axis.
