S-90769A176 Length 90 mm DIN 7504 N, ISO 7049 Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated No. 3 drill tip that penetrates up to 6mm thickness in various materials
• Superior corrosion resistance through zinc-plated steel construction for extended service life in harsh environments
• Enhanced driving efficiency with Phillips drive system providing secure torque transfer and reduced cam-out
• Optimal material displacement through thread forming design that creates strong, permanent threads without chip removal
• Maximum holding power achieved through full threading and 1.8mm pitch for superior fastening in demanding applications
• Versatile material compatibility working effectively in steel, stainless steel, aluminum, fabric, insulation, sheet metal, and wood
• Reliable industrial performance backed by DIN 7504 N certification for consistent quality and dimensional accuracy

Professional Applications & Engineering Value

These M6.3 metric tapping screws deliver exceptional engineering value by solving critical installation challenges in industrial assembly. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength for structural applications. The self-drilling tip eliminates separate drilling operations, significantly reducing installation time and labor costs in steel, stainless steel, and aluminum fabrication. The thread forming design creates precise mating threads without generating chips, preventing contamination in electrical enclosures and HVAC systems. With fully threaded engagement and right-hand thread configuration, these screws ensure uniform stress distribution and reliable clamping force in sheet metal assemblies, construction frameworks, and industrial equipment manufacturing.

Specification Summary & Compliance
