Looking to replace new bolts that were pulled out from my Toyota Hiace brake rotor that was screwed against the hub.
Having trouble identifying grade of the bolts. Its got two radial lines on the head marking, but google research showed bolt marking of 3 radial lines only which is a Grade 5. Base on rule of thumb, grade is determine by number of lines plus two, so naturally my bolt is a Grade 4, but it doesnt exist!
