    Default Heat Resistant Engine Bolt?

    Hey everyone this is my first post on this forum so I hope I'm doing it right.

    In process of changing my spark plugs and wires the other day I managed to break off a bolt head that was attached to the engine block which held a "ground" wire in place. I went in to O'Reillys and they said I could just connect the wire to this other unused hole right next to the old one and it would be fine since the wire would still be ground. So I bought a new bolt and reconected it and it works.
    The question is, the person at O'Reillys told me I needed to go to the dealership and look for a heat resistant bolt since the one they sold to me was not and would eventually melt into place on the block. Is this true? I can't seem to find any of these bolts anywhere online.

    The bolts are Hex Head Cap Screws M6-1.0 x 16mm

    Um, did they sell you a plastic bolt or something? There's really is such thing as a heat "resistant" bolt, maybe he meant heat treated or plated? But either way a metal bolt isnt going to "melt" to an engine. It might get seized in the block if it is a different kind of metal than the block and has no lubicrant/anti-seize on the threads. ie: steel bolt to aluminum block, stainless bolt to steel block and etc

    Thanks for the quick reply!
    Yeah it sounded weird to me too. I guess what I need is an aluminum bolt since the block is aluminum. I'll put some anti-seize on there too.

    You don't need an aluminum bolt or anything else special. Just put some anti-seize on it. Heat resistant bolt, that's funny

    Correct me if I'm wrong, but the 2UZ-FE uses a cast iron block and aluminum heads, yes?

    Keep in mind that most of the guys you see at the local Yahoo parts stores were more than likely flipping burgers for a living the week prior.
