S-90469A147 Length 90 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
• Effortless installation thanks to the integrated drilling tip, which eliminates the need for pre-drilling in steel and sheet metal up to 0.207".
• High torque capability and secure fastening with the external hex head and flanged design, providing a larger bearing surface and reducing the risk of loosening.
• Reliable thread forming using the BSD method, creating strong, vibration-resistant threads in ductile materials without generating chips.
• Full thread engagement along the 90mm length, offering maximum grip and load distribution for robust assemblies.
• Guaranteed dimensional accuracy and performance compliance with DIN 7504 K standards, ensuring interchangeability and reliability.
• Environmentally safe and compliant with RoHS 3 and REACH regulations, making them suitable for global supply chains and sustainable operations.

Professional Applications & Engineering Value

This M5.5 x 90mm zinc-plated steel tapping screw is engineered to address common challenges in fastening steel and sheet metal components. Its thread forming design, compliant with DIN 7504 K, produces durable, high-strength threads by displacing material rather than cutting it, which minimizes stress concentrations and enhances joint integrity. The flanged hex head with external drive allows for high torque application and prevents sinking into softer materials, while the drilling tip streamlines assembly by combining drilling and tapping into a single operation. This reduces labor time, tooling costs, and the risk of misalignment, making it an ideal choice for automotive, machinery, and structural applications where efficiency and reliability are paramount.

Specification Summary & Compliance

This fully threaded screw features an M5.5 size, 90mm length, 8mm hex head width, and 11mm flange diameter, with precision manufacturing meeting DIN 7504 K specifications for thread forming screws. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for industrial use worldwide.
