What size bolt is this?? Rear seat bracket bolt....

save me a trip to HD and tell me what size this is?

 

Go to your local ACE hardware, you most likely will not find it at Home Depot; take the bolt with you and size it there. My local ACE is excellent, and their hardware supplier is "Hillman". Your local results may very.

A good guide for the Toyotas is whatever the hex head size is subtract 4mm and that is the major diameter. Looks to be a 14MM hex head which would make it a 10MM bolt, with most likely a 1.5mm pitch or could be 1.25mm fine pitch. However, since it seems to be in the back seat area where the seat belts may have been removed it may not be metric, but SAE - possibly a 7/16" 20 threads per inch.

 

I forgot ACE has that board with the size/thread holes on it....thank you sir....

 

Hillman is the supplier for basically all bolts at the big name hardware stores fwiw
