This is the longer version of the stud that sits on the cowl behind the dash, or on the back deck along the edge of the cockpit. Sometimes the traditional length studs (3/8") aren't long enough to go through these spots, especially if there has been body work done in those areas. If so, these studs have a 5/8" long machine thread so you should have enough additional length for installation. Thread sizing is 8-32.
