Hi all,
I am installing a used hitch on my 2004 Camry LE for bicycle rack.
I have no original bolts and trying to figure out which ones I need.

I was able to figure out that one of them is M10*1.25, but the others look different. Does anyone know what types are they? Could they be not metric but standard (US)? Maybe somebody has a link to a detailed scheme of the frame?

 

Do all Toyota bolts thread into all holes?

Are all bolts the same size but some don't (perhaps the new one) thread into all holes?

Are you sure all threads are clean?

Toyota is not going to mix bolt standards.

Measure them. M8 is about 0.314 inch in dia. M10 0.3943, M12 0.472.

Use the charts below to determine if the bolt pitch is the same.

If all Toyota bolts thread into all holes and the new ones does not. Its possible the new bolt threads are slightly off.

Use a 8.8 grade metric bolt or higher.
