Bolt size

I have 2003 double cab dlx Toyota Tacoma and as I was attempting to do spark plugs there’s a bolt missing nearby and was wonder what’s the right size bolt I know it’s a 10 mm but don’t know the ]

 

Definitely not a 10mm.... 10mm hex head is different from a 10mm bolt. IIRC it should be a m6

 

Easy to measure the depth of the hole

M6 x1.0

 

Pull another and measure it? Parts Fiche?

 

I must be missing something, but the two pictures look like they are in different locations.

The missing bolt in the second picture looks like a wire harness retainer bolt and there is a broken plastic protector just behind it. Is that correct? If so, not need to replace the bolt. I is just to secure the wire harness.

 

Like this one:

 

Don't bother with the one that's missing. It just holds the wire loom/casing that's just above it but the "ear" on yours is already broken and can't be held down. Mine completely deteriorated a while ago and I just wrapped it with common 3/4 accordion wire loom.

 

I found the screw! It was hidden in the very middle and was able to grab it with my hands and put it back

 

As long as your happy that is all that matters.

What did you use to secure the wire harness??
