The b&m-TIGHT® is our innovation in the field of direct screwing M8-M14. It was specially developed for aluminum-steel hybrid applications. In contrast to "trilobular" screws, the b&m-TIGHT® has a circular cross-section covering the entire threaded area. The complete flank overlap enables a process-safe, robust screw connection that achieves impressive preload forces. Another special feature: with an appropriately adapted core hole, the b&m-TIGHT® is self-sealing against gases and liquids.
