RIVNUTS FLAT HEAD OPEN

The Rivnut is a one-piece internally threaded and counterbored tubular aluminum rivet that can be pulled up or headed while working entirely from one side, forming a bulge or head on the blind side. This upset is large enough to resist being pulled through metal or plastic even under conditions of eccentric load. It overcomes the difficulty of installing brackets, handles or other attachments to tubular pieces.

Rivnut is threaded onto pull-up stud of a hand or power- heading tool. Rivnut on header tool mandrel, inserted in drilled hole ready for installation. Arrow indicates direction of mandrel movement as tool is operated Mandrel retracts pullingthreaded portion of Rivnut shank toward blind side of work, forming bulge around unthreaded shank area. Rivnut is clinched securely in place. Unthreading the tool mandrel leaves internal Rivnut threads intact, unharmed BLIND NUT PLATE Installed Rivnuts also serve as blind nut plates for simple screw attachments RIVET/RIVNUT BACK MARKERS Used to locate pre-drilled holes in the wing ribs, fuel tank covers, panels, skin. Pre-drill the ribs, screw in the back markers, lay the skin sheet over the top, tap with hammer, turn the sheet over, and drill the holes. This is especially useful for rivnut installation.Due to the large size of the hole required, small errors in location can lead to the "Oh darn, I missed the rib syndrome". Backmarkers save you hours of frustration. 2 sizes of threaded backmarkers are available. We recommend using the 04-00131 for wing ribs. Drilling the wing ribs with a 3/32" drill. Drop in the back markers. Mark the skin by taping with a soft hammer. Turn the skin over and drill the skin with a 3/32" drill. Cleco the skin into position enlarge the holes with #30 drill & cleco. Now you are ready to rivet.
