47-55.1 Lost a Nut.....

[Dachshund]

I was chasing threads for the door hinges (cab side) yesterday, and found out the bottom nut on the lower passenger side pocket is GONE. What is the easiest way to fix this without tearing the whole thing apart? It was in there a couple weeks ago, but not anymore.

find a weld in nut at the local hardware store or industrial supply store. they recess into a hole & have a shoulder that you weld to the door pillar

They do sell 3/8 -16 rivnuts. I'd check Fastenal or a local fastener supplier for the availability of singles though. This Amazon link is pretty neat as it shows quite a bit of info including a chart that shows what size drill bit you need to use.

The weld in isn't a bad idea though.

Hello Dachshund. I had the same problem on my truck. What I came up with could help you. No welding, strong, adjustable. Just some fab work.
Material 1/4". I hope this helps. Same for left or right upper or lower.

I was thinking the same as Clarence with the steel plate behind. nice and strong. I have also used a nut welded onto a short piece of flat bar so I can get the nut into position by holding the flat bar. once the threads are started the flat bar turns and jams against a closeby object and acts as a "wrench" to hold the nut until tight. some cars use this style of idea for holding the bumper bracket nuts on inside the frame. you may be able to make some up quick and use a body washer as a back up so the nut doesn't pull through the steel bodywork when bearing down against. glue the washer on the back side of the hole first so it doesn't fall down. I have also used a piece of a nitrile glove inside the box end wrench to hold the nut from falling out until the nut is in position for the bolt. a flange nut is handy here so the nut doesn't push right through the box end.

Great Ideas, guys! I haven't finalized a plan yet, but MIGHT try a flange nut, and drill 3-4 small holes to weld from the outside......
