What is the proper name for the type of fastener that is commonly used with sheet metal screws in applications where a nut and bolt can't be used. they ware always made of spring steel and can be flat or slightly curved with different sizes for different size screws and applications, I loked at McMaster-Carr but didn't really know what to call them. Thanks.

I have used CLECO temporary fasteners to hold sheet metal together

I think that is what he is looking for, also commonly sold as speed nuts or push nuts:

rectangular push nuts.

Thanks to all who responded. Rectangular push nuts is what I was looking for.

I don't believe Ford ever used such a fastener.

D nuts and maybe not on a T but there were a number of them used on the Model A.

Larry, I agree with you, but I was going to use them in a place no one would ever see or notice.

PAL nuts? Push And Lock?

In the UK they are spire nuts
