Cylindrical nut FLANGEFORM®

metalthreadedhydraulic

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. - Advantages : • Hole Preparation: A pre-punched or drilled hole is required with a tolerance of +/- 0.1mm. • Sheet Preparation: Flangeform® is suited up to 80Rb, in some cases a pre-form may be required. • Installed by progression, transfer, off-line mechanical / hydraulic presses using autofeed or manual techniques. • Mini-Die (bottom tool) will vary depending upon the material thickness, hole size and hardness
