I never thought of using art work to simulate windows!

Each rivnut has a specific size hole that is required for proper use. You just need to make sure you have the proper size drill bit if the holes are not the correct size for the rivnut that you are placing.

thanks ultane. That makes sense. How does one determine the correct bit size based on the nomenclature of the specifications of the rivet.....?

for example Shadetreemech posted a link to Amazon for this:

Ribbed "K" Series Rivet Nuts - Material: Steel-Yellow Zinc, Thread Size: 8-32 UNC, Grip Range: .080-.130, 100 Piece Box

which of these numbers determines the correct drill bit size? (.080-.130? is this millimeters?) how does that translate to bit size? why is it a range? seems like the tolerance would have to be pretty exact in order for it to work.

anyone with satisfactory results with these fasteners? I think Orton used a similar device to fix his rear handles?

lepelch,

It's my understanding that 'Range' refers to the range of thicknesses (mm) of sheet metal that a specific rivnut is suitable to be used. It's also my understanding that the insertion tool has different size mandrels that screws into the different size rivnuts, and then the tool pulls the mandrel with a considerable amount of force, causing the rivnut to 'bulge' behind the sheet metal, holding the rivnut in place. The portion of the rivnut that bulges has no threads, so the mandrel is easy to unscrew. I assume that the larger the bulge and harder the rivnut metal, the more of a load each rivnut can hold before pulling out of the sheet metal. The ribbed rivnuts are a little bit more resistant to spinning, after installation, when a screw is being tightened down to hold something in place.

I bought my rivnut tool at the local 'TACOMA SCREW' store in Boise before moving east. I asked the salesman at the desk which size bit that each of the rivnuts a required when I stocked up before moving. I assume that you can ask any Amazon vendor that is selling them, which size drill bit is required for each size rivnut. One of the rivnuts took a weird size bit, but I can't recall which one it was.

Someone here probably knows which size rivnuts will fit into the various holes located underneath the black sheeting in the cargo van. It has also been suggested to use a strong magnet along the sheet metal to capture the metal filings as the fall inside the metal posts, and then maneuver the magnet to a hole to acquire the metal shavings so that they don't rust inside the hidden recesses of the van.
