What bolts do I need for the side steps?

I bought 3rd gen predator steps for my 2015 Tacoma.

Now I need to install them. Are they the same size as the 3rd gen bolts? M8 1.25 x 30mm

Are they stainless or regular steel? Do I need a washer?

I have asked on FB and Reddit and no one knows.

 

That is the size for the factory tube steps on a Gen 2 truck. Sounds good to go.

I used SS when I installed my second hand tube steps.

 

The OEM bolts are plain black bolts M8x1.25

 

I recently did this and bought SS bolts and washers from Amazon

Yes, the bolts from the 3rd gen will ft. The bolt sizes are M8x1.25x20mm. Here is a link to the the factory Toyota instructions that confirm the bolts sizes are M8X1.25X20mm (Item #2).

I took some bolts
Took my steps
Threw them in the garbage which is place for them
Installed sliders
Happily ever after

 

I suggest cleaning the threads and anti-seize after.
