This is an old thread, however it brought to mind that some of the "Bubble packs" that are prepackaged in hardware stores have the small installation tools included. A grade 8 socket head cap screw, a hex shaped coller with a serated tip to prevent the insert from spinning while installing. This saves the need for purchasing expensive toools and still gives a good result. Most frame rails are a minimum of .120 wall and will accept a tapped 10-32 screw for securing fuel lines etc without the need for Rivnuts.
