Self-drilling screw wood / metal, T25, 6 grooves, 4.8x60, wings

Self-drilling screws with wings are used for connecting wooden elements made of solid wood, thin-walled sheets and especially large-area wood-based materials with beams made of standard steel with a thickness of 3 to 4 mm. Solid wood elements - they can be made of hard and soft woods (these are parts of profileings, fencing, etc.), which can be anchored to a thin-walled steel profile of the L-angle, strip, jöckel type. Large-area materials - these are, for example, BIO boards, OSB boards, chipboards and other dimensionally stabilized materials for various types of steel beams. Note: Dimensionally unstable large-area materials can be anchored with these screws only after consultation with the supplier of these materials. Advantages: Combining multiple operations into one - saves time and costs. The construction of the screw reduces the splitting of the material - it can be anchored in close proximity to the edges of the boards. The wings near the drill bit are used to mill the material around the screw shank. After passing into the beam, it breaks off and the thread is firmly cut into the material. The gap between the shaft and the anchored material eliminates dimensional changes caused by the anchored material or from different types of loads.
