EJOT Spiralform® screws are special fasteners for reliable and trouble-free metal joints, especially in steel and and stainless steel. Thread-forming and fastening are only one step with this screw. An accurate, tight fitting thread with high strength properties is always formed. This guarantees optimal resistance against loosening under dynamic stress.
EJOT Spiralform® screws have four burlings at intervals of 90° which run across the thread in a spiral. This way the VDE requirements for the use of self-tapping screws are met. The Spiralform® Plus point causes very low thread-forming torques. Due to the special formed start of the thread in combination with the circular thread cross section the screw can be applied much easier. The circular cross-section also enables a full thread engagement which results in higher strength properties. High process reliability and consistent thread quality are realised.
