The open recess design allows for heavy coatings and paints buildup without affecting fastener driveability. Other features include lower weight and a low radar return signature. The system minimizes cam-out and reduces damage to the surrounding airframe. Its off-angle driving capability is an advantage in cramped applications. BS EN 4847 walks you through the requirements (configuration, dimensions, masses), toleran...
