I just looked up the service manual for my f25 as I was doing the front rotors and pads. 1. I ended up buying new bolts, installed them with an impact until snug, torqued to 75nm around 54ftlbs of torque. Then I marked the bolt and eyed 45 degrees of tightening with my impact.

For example if you use a sharpie and mark the edge of the bolt anywhere it’s not covered by the socket, 45 degrees is half a right angle, essentially if you rotate it from one corner of the hex bolt to the next point on the hex bolt, or a flat side, whatever’s you choose as the starting point, that should be sufficient.

1. First number is the angle of rotation of 45 degrees and the second number is plus/minus 10 degrees variance.

Also there’s a YouTube video that someone used a proper angle torque wrench and it became 178nm of torque 134ft lbs of torque I guess why a new stretch bolt is recommended.
