Floorboard D-Nuts
I need to replace a few floorboard D-nuts, my question is how do you install them? I would love to see what people use to set the nuts in place. Do you use some sort of tool, or improvised piece of steel as a bucking bar? then what do you strike the top with? Do you use heat? It appears the original ones are swaged in somehow and I'm curious what your methods are. Thanks!

Re: Floorboard D-Nuts
1930 coupe,
What size steel ball did you use? If you did it again, would you use the same size ball or a smaller or larger one? It seems like grinding a flat spot on the ball would help keep the C clamp from slipping off when it it tightened. I will need to install a D nut in my CCPU' floorboard in the future. Rusty Nelson |

Re: Floorboard D-Nuts
I saw a C clamp at the flee market the other day that was missing the flat swivel part, leaving just a nice round ball on the end of the screw. This would be ideal for spreading the D nuts.

Re: Floorboard D-Nuts
It seems to me that a steel ball large enough not to touch the lower part of the D nut would hit the side of the cross-sills or subrails. I tried a golf ball, which is about 1 5/8" in diameter, and it was quite a bit too large, as it hit the side of the subrail big time.

Re: Floorboard D-Nuts
1930 Coupe,
I understood the two step process, but I thought a larger steel ball would be necessary to push out the top of the D nut than the ball size in the picture of your last post. The ball in your picture looks to be about 3/4" in diameter which would probably fit along side the edge of the subrails or cross-sills. I need to get a steel ball and would like to get the right size the first time, Would it be a problem for you to measure the steel ball you used since you have successfully installed a D nut(s).

Re: Floorboard D-Nuts
Thanks for providing the measurement of the steel ball you used. I should be able to install the D nut with the help you provided.

Re: Floorboard D-Nuts
Wow! Great idea. I was about to change out 6 or 7 this weekend and I bet I can do it now in no time.

Re: Floorboard D-Nuts
I just cut the rounded head off a carriage bolt and put it in the vise to spread the flange of the nut.
