The Stovebolt Site Forums The Parking Lot Panels 'N Burbs What is the official name of this type of fastener

Hello,

What is the official name of this type of fastener? Picture of fastener

The fastener is from a:
1954 Chevrolet panel truck drivers side rear side panel inner compartment, the fastener is for rear fender attachment.

Is the nut holder spot welded into place?
How is it held into place?

Thanks

I may be wrong , but i think its a "capture nut"?
Yes, its spot welded into place.
Good luck with your truck,
Marty

That's what I was gonna say, captured nut.

it's a weld nut that's spot welded in a precise position, a captive nut is one that is inserted in a hole and held by knurling

Bill

Is it one of these?

Hello

From the names that all you posters suggested.

The closes I could come up with is pictured in these links below:
Looks like Ford & Willy's army jeeps used them.

The thing is they have a square stamped tube on one side of the cage and I still have my fender on the truck so I can't see if the
the other side of the metal the nut is welded to has a square punched out hole.

If anybody has the rear fender off their 47-55 1st panel truck or has pictures of the original nut holes, check to see if the nut holes are round or square.

The factory worker, after punching out the hole in the metal panel must of spot welded the nut cage onto the metal panel , then inserted the square nut into the cage then bent the tabs over to hold the nut. If they spot welded with the square nut in the cage, the nut would not be able to float.

Thanks,

Here is a picture of an actual retainer nut that Ray Stanley sells.

I'm going to spot weld mine into place where needed.

I know it's not correct, but I have recently used T nuts, available at the hardware store, on another project. They are designed for wood, so I flatten the barbs, and tack them in place. Worked great for attaching floor panels to sub-floor.
