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. Item #03750, Frame Rivet Bolt, $2.99 each.Ah, the rivet nut. The rivet and bumper gusset shown in the pictures is not included. The bolts are the same diameter as an original rivet so no drilling should be required if installing where an original rivet had been used. The nuts are out of sight so they need no modifications once in place. I have experimented with different lengths and have found this one to be the best length to fit through the frame and most items shuch as the bumper gussets and rear crossmember with enough threads to use the washers and nut. I’ve used these and never had anyone call me out for not having an actual rivet in place.Įach bolt includes a flat washer, lock washer, and nut. I believe these could be used in a factory class restoration and go unnoticed. These bolts are strong for high stress areas and once the hex socket is filled in, will replicate a rivet’s appearance close enough to fool most everyone, including the jeep police at judging events. This is the best method I have found to replace rivets. Most of us jeep guys do not have the tools or capacity to replace the frame rivets with actual rivets. With the other bolts on the market, you will have to grind them out like a rivet. Also, if you need to replace a damaged item like a bumper in the future, you can dig the body filler out of the hex socket and remove the bolt. If you need to remove the bolt to make adjustments during restoration you cannot do that with the break away bolts or the bolts with no sockets in the head. The advantage to this bolt is that it is not a one time use item like the break away bolts or bolts with no head socket that are available. It can be sanded down to look exactly like a rivet. You can use the filler to build up the head according to your liking. Once you have the bolt and nut tight enough for your application, you can fill the socket in with JB Weld or body filler. The beauty of this bolt is that it has a hex socket in the head that allows you to tighten the nuts snuggly. This bolt has a head that is very similiar in appearance to the original rivets used on the early jeep frames. Also great for bumper gussets and rear crossmembers as well as body supports, etc. This high quality bolt is an alloy material and stronger than grade 5 or grade 8 bolts so this bolt can be used in the high strees areas like holding on a spring hanger or frame crossmember. High quality bolt to replace the rivets in a Ford GPW, Willys MB, CJ2A and others.
