Thankfully the chassis was saved, I just want to try improve it. It is a mystery what went on with this chassis, but it has obviously lead a very hard life and a lot of work went into saving it. You’ll see just how easy it is to install these specialty fasteners without special tools - it just requires a little DIY ingenuity.Bolts in chassisThose who have read this thread from the start will have seen that I have just acquired a GPW chassis that had been "restored" decades ago using large bolts in place of every single rivet. But a picture's worth a thousand words so below is a video demonstrating the steps we’ve outlined. You can use this same technique to install rivet nuts in steel, plastic or other materials where a threaded hole is needed on your truck and other methods of attaching parts or accessories just won’t work. Now you can just back the bolt out of the insert. If it’s not tightened enough, you risk the nut insert spinning in the hole later – which you definitely don’t want. There’s no need to go ‘gorilla’ on it, just stop when it won’t tighten any more. This will collapse the rivet nut on the back side and lock it into the hole. Now, while holding the box wrench, start tightening the bolt. Put a wrench on the oversized nut to prevent it from spinning and a socket on the bolt head. With your DIY tool assembled in the order described above, thread it into the insert until it bottoms out. This won’t work well if the hole is too big. (1) Nut - larger than the bolt threads so it will just slip over the bolt. (1) Flat Washer for under the head of the bolt. (1) 1”-2” bolt that is the same size as the threads of the rivet nut. Here's what you'll need make a cheap and simple tool Here, we’re going to show you how to make a DIY tool using a nut, bolt, and two washers found at any hardware store. Unless you plan to install a lot of rivet nuts over time it probably doesn’t make sense to go out and buy a tool to do it. Here at our facility we use an expensive, special tool to quickly install rivet nuts where needed. If those cases, you’ll need to install one or more of the inserts we provide. Occasionally, the truck may come with holes in the panel but no threaded insert. Our S/I Side Steps for trucks utilize these factory-engineered locations (and others) for easy and secure installation of the steps. 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. Threaded inserts are used by truck manufacturers in numerous places to attach parts and accessories to sheet metal components. Once assembled and properly mounted on your truck, it makes for an extremely strong and rigid installation. 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. Rivet nuts are often used in thinner gauge materials where strong, load-bearing threads are needed to fasten pieces together or where there’s no access to the back side for a traditional hex nut. Initially they were sold under the trademark name RIVNUT®, but today you’ll find various brands in numerous shapes and sizes as a type of blind fastener. Sometimes they're simply referred to as threaded inserts, or generically as Nutserts® (which is also a trademark brand name). This handy little fastener was developed by BF Goodrich in 1936 to mount rubber de-icing boots to the leading edge of aircraft wings.
