Due to the tempreture fluctuation of hot and cold on an exhaust so close to the engine is this bolt ok for holing the downpipe/silencer to the manifold?

they do a 75mm long bolt. I've been advised to use a brass nut as it wont seize onto the bolt. Will the above bolt be ok with the heat fluctuation?
