I bought these to replace the origional bridge bolts and mounting bolts. They are hardened chrome and look nice and should stay looking nice for time to come.The problem I have had was the smaller brake pad pins did not work. The head is smaller than the original, the pins were a little shorter, the threads were a little larger. Maybe its in the manufacturing inconsistencies or lack of quality control. They got stuck in my caliper due to the inconsistencies and I had to pay for a bolt extraction from a machine shop.
