FLANGEFORM® CLOSED END NUTS
FLANGEFORM® Closed End Nuts are threaded fasteners with unique ribs designed for installation into thin gauge materials. The fastener plunges the pre-punched hole and wraps itself around the material whilst the ribs embed themselves providing an integral high-strength attachment point. The one piece design provides a water tight seal, ideal for roof rack applications or when sealing is required.
