Hi everyone. I found these two screws lying around when I was doing my brakes (front). The right brake after removal of old and install or new. I can't figure out where they go. They may go elsewhere on my car, but I found them there.

 

They look like caliper bracker screws at first blush. Definitely hefty. But, they're way too clean to have been on the car for a long time, so I'm not sure. Are your brakes working? What exactly did you touch or replace during the brake job?

 

Thanks. They are not caliper bracket screws. The bracket has 2 screws, and caliper has 2. I can't see where these would go on my car, anywhere.

Brakes are working. changed brake fluid, brake pads and rotors on all four wheels.

 

They don't look like Mazda bolts either.

Have seen similar ones on Toyotas though?

 

My RX8 has bolts like this for the door hinges. The blank space above the threads, but below the head, is used for indexing.

 

Thanks
