06 3743 NZ. pub. 10/15 © ASSY ® 3.0 SK A2 PARTIAL THREAD Application: The ASSY ® 3.0 SK A2 with a large disk head especially suited for photovoltaic/ woodworking/carpentry trades for screw connections outdoors, for humid rooms and salty atmospheres. Tip: The 30° tip enables precise starting. Screw with ring thread in tip area, which greatly reduces the splitting forces of the wood, especially in the edge area. The screw- in torque is considerably less than with conventional particle board screws and extends the service life of the processing machine and the bit insert. Thread: Easy screwing in thanks to asymmetrical entry thread. End mill: The end mill after the thread reduces the screw-in torque by 20 %. Head: Large disk head with AW ® drive • Optimum power transmission • Optimum centering • Long service life • Even distribution of power prevents the surface coating from being damaged Material: Corrosion-resistant, austenitic stainless steel A2 (1.4301, 1.4567) Note: Austenitic stainless steel is characterized by a high corrosion-resistance to aggressive industrial air, ocean climate, line, river, sewer and salt water and wood containing tannic acid. It is conditionally resistant to acid and not suitable for atmospheres containing chlorine gas.

Rustproof stainless steels (e.g. Material No. 1.4016) are recommended there for use in the atmospheric area only for use in a rural environment, and here as well only with great restrictions. We therefore recommend only using austenitic stainless steels for outdoor applications while taking the environmental conditions into account. The stainless steel A4 (0169 005 …) is especially suitable for use in an industrial atmosphere and for use near the sea. Stainless steels for various ambient conditions (www.edelstahl-rostfrei.de, Information Leaflet 828) N = Lowest corrosion loading within the respective environment, characterized, for example, by low temperatures and low humidity M = Medium corrosion loading within the respective environment H = Higher corrosion loading within the respective environment, e.g. due to continuously high humidity, high ambient temperatures, especially aggressive air pollution x = Basically meets the requirements, however less expensive steels could also be sufficient + = Probably the best choice of materials with regard to corrosion resistance and costs (+) = Sufficient behavior, provided certain precautionary measures are taken. Smooth surface finishes and regular cleaning are especially important – = Probably heavy corrosion ETA-11/0190 ASSY ® 3.0 particle board screws are optimized for use in wooden materials. When used in plastic anchors, a reduction of the load-bearing capacity is possible. For this reason, we recommend only using screws without optimized thread tips (drilling tip, counter thread, ring thread, ground corrugated, self-clearing groove etc.), e.g. achnor screws, Pre.
