o2 thread size

[MSRmechanic]

Hey, i searched and couldnt find exactly what i was looking for.

I managed to loose the nut and bolt that attach the downpipe to the o2 housing. i was doing a motor swap and i had the nut on the bolt, and now they have dissapeared.

Basically I just need to know what the thread size is for these. thanks in advance.

Figured i would post this incase people search and find this.

The bolt is a 17mm. if you have a bolt bin, look for 17s and one will fit. when i know the thread pitch i will post that too.
