o2 housing bolt size

[dan2288]

anyone know the size of the o2 housing bolt? Im getting ready to put on a fp race mani and need to use those bolts for the rear. I will try to get then at a hardware store since they are 7 bucks a piece! Its gonna cost me about 70 shipped to get new gaskets and the two bolts so If I can get them at the store for cheap then I will. I will make sure I get 10.9 grade bolts thou.

how long are the stock bolts?

 

[JusMX141]

10mm x 1.25.

The stock manifold bolts are approx. 80mm in length, stock o2 housing bolts are approx. 35mm in length.

I might have just read it wrong, but I need a nut and a bolt for the O2 housing to hotside cause there's a leak there.
The size is 10mm x 1.25, 31mm long?
