S-94209A651 M3.5 x 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP15 drive, reducing cam-out and tool wear for reliable installation
• Enhanced corrosion resistance from zinc-plated steel construction, extending service life in harsh industrial environments
• Secure fastening in soft materials like aluminum, brass, and copper due to the tri-lobe shank design that forms strong threads without pre-drilling
• High-strength thread engagement with fully threaded M3.5 coarse pitch (0.6 mm), ensuring vibration resistance and load distribution
• Easy alignment and reduced head protrusion with rounded pan head profile, ideal for applications requiring a low-profile finish
• Consistent performance with precise length tolerance (-0.8 to 0 mm), providing reliable fit in automated assembly processes
• Compliance with global safety standards including RoHS 3 and REACH, ensuring environmental and workplace safety

Professional Applications & Engineering Value

These M3.5 tapping screws are engineered to address common challenges in fastening aluminum, brass, and copper components, where traditional screws may strip threads or require additional tapping steps. The thread forming tri-lobe shank displaces material to create strong, permanent threads without chips, eliminating cleanup and reducing assembly time. Made from zinc-plated steel, they offer durability against corrosion in electronics, automotive, and HVAC systems. The Torx Plus IP15 drive ensures high torque transfer, minimizing slippage and damage to drive systems, while the blunt tip and fully threaded design provide consistent holding power in soft metals, making them ideal for high-volume manufacturing and maintenance applications.

Specification Summary & Compliance

This screw features Metric M3.5 coarse thread with 0.6 mm pitch and a length of 8 mm, adhering to standard dimensional tolerances for reliable performance. The tri-lobe shank cross-section and thread forming method ensure precise fit in pre-drilled holes. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for industrial use without hazardous substances. The right-hand metric thread and pan head style support efficient installation in automated or manual settings.
