S-90469A156 Length 45 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 demanding industrial environments.
• Efficient self-drilling capability with a No. 3 drill tip and 11mm length, enabling quick installation without pre-drilling in steel and sheet metal up to 0.236" thick.
• Enhanced grip and load distribution from the integrated flange, reducing the risk of loosening under vibration and improving joint integrity.
• High-strength thread forming design (BSD type) creates secure, permanent threads in materials, providing excellent pull-out resistance.
• Easy installation and removal with external hex drive and standard right-hand thread, compatible with common tools for fast assembly.
• Full thread engagement along the 45mm length ensures consistent clamping force and reliable fastening in various material thicknesses.
• Compliance with international standards including DIN 7504 K, guaranteeing dimensional accuracy and interoperability in global applications.

Professional Applications & Engineering Value

These M6.3 zinc-plated steel tapping screws are engineered to address common challenges in steel and sheet metal fabrication, such as the need for rapid assembly and vibration resistance. The thread forming design eliminates the requirement for tapped holes, reducing labor time and tooling costs while creating strong, wear-resistant threads. With a flanged hex head and external hex drive, they provide secure torque transmission and prevent sinking into softer materials. The No. 3 drill tip penetrates up to 0.236" thickness efficiently, making them ideal for HVAC, automotive, and construction applications where durability and speed are critical. Fully compliant with DIN 7504 K specifications, these screws deliver consistent performance and reliability in high-stress environments.

Specification Summary & Compliance
