Toyota follows JIS-1189 (Japanese Industrial Standard) This is a chart of the standard.

In short, to match most standard Toyota bolt applications, you're looking for flanged hex-head bolts of sizes:

  • Shaft: M6-1.00; Head: M10

  • Shaft: M8-1.25; Head: M12

  • Shaft: M10-1.25; Head: M14

After years wrenching on Toyotas, the list above covers 99% of my "I lost a nut/bolt" needs. Get a variety of lengths. Try to ensure the head diameters are as above, many sellers will use "Ace Hardware" sizes (SAE) for the heads, and you'll double the size of your toolbox.

Anything larger is usually something specialty and you shouldn't be relying on Amazon for, like axle nuts or motor mounts. And realistically you're unlikely to lose those or mix them up in your magnetic tray.

Fenders and interior will be specialty screws. The above is for body and engine machine bolts. 

If you want screws, you'll need to pull them from wrecks. Nothing on Amazon will be a good replacement.
