Slide the flat washer onto the bolt. Now stick the end of the bolt through the hole in the steel strip. Thread the nutsert onto the end of the bolt until the end of the bolt is flush with the bottom of the nutsert.
Slide the steel strip and the flat washer up against the face of the nutsert. Lubricate the bolt thread that's now exposed between the nut and the flat washer with a molybdenum lubricant doing it at this point minimizes getting lubricant on the nutsert threads. Thread the nut down until it touches the flatwasher. Use two wrenches. One to hold the head of the bolt stationary.
One to turn the nut. The steel strip should also be held stationary. As the nut is turned, the bolt will be pulled straight out, collapsing and seating the nutsert. When the nutsert is very tightly seated, loosen the nut a little and then unthread the bolt from the nutsert. This handy little fastener was developed by BF Goodrich in to mount rubber de-icing boots to the leading edge of aircraft wings.
At Spyder Industries we use them in the steel tubing of our headache racks for pickup trucks so that you can bolt the adjustable bed rails or mounts to the bottom of the rack. Once assembled and properly mounted on your truck, it makes for an extremely strong and rigid installation. Threaded inserts are used by truck manufacturers in numerous places to attach parts and accessories to sheet metal components.
For example, on late model Dodge Ram trucks you might find nut inserts installed by the factory on the back side of the rocker panel for mounting side steps.
Occasionally, the truck may come with holes in the panel but no threaded insert. Here at our facility we use an expensive, special tool to quickly install rivet nuts where needed. Push the rivet nut into the hole. A snug fit is better than a sloppy one.
