S-90469A148 Length 100 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated No. 3 drill tip that penetrates steel and sheet metal up to 0.207" thickness
• Superior corrosion resistance through zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced installation efficiency with external hex drive design providing secure tool engagement and high torque transmission
• Increased joint stability through flanged head design that distributes clamping force and prevents loosening under vibration
• Full thread engagement capability with 100mm fully threaded shank ensuring maximum holding power across the entire fastener length
• Reliable thread forming action with BSD tapping method that creates strong, precise threads in base materials without chip removal
• Regulatory compliance assurance meeting DIN 7504 K standards and environmental directives including RoHS 3 and REACH

Professional Applications & Engineering Value

Engineered for steel and sheet metal fabrication, these M5.5 tapping screws deliver exceptional value in industrial assembly applications where speed and reliability are critical. The zinc-plated steel construction provides durable corrosion protection, while the thread forming design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs. The combination of fully threaded configuration and flanged hex head ensures uniform stress distribution and prevents pull-through in thin materials. With their self-drilling capability and external hex drive, these screws are ideal for high-volume production environments, construction projects, and metal framework assemblies where consistent performance and regulatory compliance are mandatory requirements.

Specification Summary & Compliance

This M5.5 x 100mm metric screw features precision right-hand threads with fully threaded shank and round cross-section. Manufactured to DIN 7504 K specifications (equivalent to ISO 15480), it ensures dimensional accuracy and performance reliability. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for industrial applications with strict compliance requirements. The BSD tapping screw design with No. 3 drill tip and thread forming method provides consistent performance in steel and sheet metal applications up to the specified maximum drilling thickness.
