- Countersunk bolts for space restricted locations (e.g., near valves or bulkheads)

- Open design allows better access to the bolt removing tools (e.g., nut splitters)

- Designed to be reusable multiple times

- Can be left in place for an extended period of time preserving flange integrity

Cost effective
