ABSTRACT:
A weather tight fastener, for joining two or more adjacent members, having a flanged sleeve member which is disposed through aligned openings in the members and a rod member having an enlarged end, engaging a portion of the tubular member for collapsing the unflanged end of the tubular member in a controlled fashion. The end of the rod member which is not enlarged, projects from the flanged end of the tubular member and is engaged by a holding plate which is slidable in one direction only. Disposed between the slidable holding plate and the exposed surface of the members to be joined are a rigid washer and a resilient washer which are necessary for proper setting and providing a secure weather tight seal. The rigid washer has a counterbore of the same general size as the flanged end of the sleeve. The steel washer is disposed with the flanged end of the sleeve nested in the counterbore. The rod member includes a breakneck groove portion which breaks away from the rod member when the fastener is secured in place. When set the rod member is drawn through the sleeve member and the slidable holding plate is forced down the rod member to engage a portion of the rod member beneath the breakneck groove. The slidable plate member thus securely holds the rod member within and in engagement with the sleeve member when the fastener is in place. The surfaces to be joined are thus held both by the collapsed sleeve and also by the slidable plate member acting through the steel washer, which engages the surface outside of the sleeve flange area.
