Does anyone know the bolt size for the D-rings in the bed?

Need some help...I did some searching and I couldn't find any info on what the actual size of the bolts are that hold the d-rings down in the bed. I tried M12 1.25 and M12 1.5 and neither of them will screw down into the bed. I need to replace the bolts, but I can't find any info.

What's weird is the bolt that came out will actually screw into the bolt gauge but the bolts I bought won't screw down into the bed.

Thanks for any help.

 

It's probably a 12x 1.75 coarse thread.

pull one out, go to the hardware store and match it up.
