I've ordered 2 new caliper carrier bolts but they won't arrive today as I needed. I've found a high tensile steel bolt of the same length and width but a difference of 0.25mm thread pitch and yes it's not an automotive bolt but I guess a general or construction bolt.
I'm confident they will screw in (maybe not though) could I get away with using these for a days or two light usage in the car or would they just not fit?
I know it's not ideal and when proper bolts arrive they will be swapped out, so in about 4 days time.
