    Intake grate bolts?

    I bought some new SS bolts for the intake grate. A4 -A2-70 bolts. So for chits and giggles I put a magnet to them and yup little to no magnetism.

    But the OEM bolts stuck to the magnet like mad. almost as if they are steel!

    are they...

    The stock bolts are steel with some sort of coating.

    Hey Rich, do you think they are steel bc they are stronger than SS?

    I have the new SS bolts in there now...

    a Bolt expert here on the forum told me that rolled threads bolts, the one with washer built in are weak where the washers are.
    I didn`t think there would be any issues at 64 inch pounds.
    but I changed them anyway...!

    Stainless is fine specially for that app ,, they used steel because it's cheap
