This Round Head Six Lobe Type 17 Self Tapping Screw is manufactured from SUS304 stainless steel, providing corrosion resistance and mechanical strength. The head design features a round head with a six-lobe (Torx) drive, which allows for high torque transmission during fastening and reduces the risk of cam-out. The screw specification is M5-2.0*55, featuring a Right And Left Thread design that aids in balancing stress or providing anti-loosening properties in specific applications. The point is designed as Type 17, characterized by a cutting notch that facilitates efficient chip evacuation during penetration into wood or plastics, reducing driving resistance.
Application Fields
Due to its material properties and thread configuration, this screw is widely used in outdoor railings, decking, landscape timber structures, and pressure-treated wood projects. The Ruspert coating makes it suitable for complex climatic conditions, including coastal facilities and high-humidity areas. Furthermore, the Right And Left Thread configuration is applicable in furniture manufacturing and interior decoration where resistance to vibration loosening or bi-directional stability is required. It is also suitable for fastening plastic profiles and soft metal substrates.
