D-nut / Clinch nut
I would like to replace some of the D-nuts or Clinch nuts in the sheet metal lip that holds the floorboards. What is the method to remove and replace them?

Re: D-nut / Clinch nut
I think the easiest way is to carefully grind off the peened-over lip of the old one, until you can see the outline of the "D" shape, and then just tap them out. Need to be careful to only grind the "D" nut lip, without thinning the sheetmetal. Then the new "D" nut can easily be slipped in and peened over.

Re: D-nut / Clinch nut
The D nuts get peened over but what holds the nut flush while it gets peened. Is there a tool that holds them in place or a tool that can roll the lip over? How was it do when they were made?

Maybe someone with a photographic memory, or at least superior search powers, can help out. |

Re: D-nut / Clinch nut
1930 coupe,
Nice find. I was looking for this string, but evidently I wasn't using the right terms(s) for my search. Thanks - I remember the string, but couldn't find it. Since you posted the ball bearing response, I guess you knew the right terms. Rusty Nelson |

Re: D-nut / Clinch nut
I have always had trouble getting the D-nuts tight. Especially if you peen them over and if loose they will chip the new paint as they slide around before /during assembly. I have also ran into the Brass ones. So I have used silver solder in places like the deck lid for rumble hinges where peening is out of the question.....just a thought!

Re: D-nut / Clinch nut
I just backed them up with a body dollie and hammer carefully on them until they're tight and uniformly "mashed". I can't say that any of them ended up loose that way; they all seemed to be pretty snug for me. I think if you grind the sheetmetal too thin to remove the orignal nut, then it'll be a lot more likely that the new one could be loose.
It seems to me that the originals must have been installed with some sort of press or pneumatic hammer fixture, as they always seem very uniform w/o the look of someone rapidly hammering on them. The "mashed" portion is always perfectly round and smooth in the ones I've looked at. |
