S-94209A685 M4 x 16 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior thread forming capability in aluminum, brass, and copper without pre-drilling, reducing assembly time and labor costs
• Enhanced torque transmission with Torx Plus IP20/T20 drive system, minimizing cam-out and tool wear for reliable fastening
• Exceptional vibration resistance thanks to tri-lobe shank design that creates secure, permanent threads in ductile materials
• Complete thread engagement with fully threaded design along the 16mm length, ensuring maximum holding power throughout the fastener
• Durable corrosion protection through zinc plating, extending service life in various industrial environments
• Optimized for high-speed assembly with coarse 0.7mm pitch metric threads that enable faster installation in soft materials
• Regulatory compliance assurance meeting RoHS 3 and REACH environmental standards for global manufacturing applications

Professional Applications & Engineering Value

These M4 metric tapping screws are specifically engineered for challenging applications in aluminum, brass, and copper components where traditional fastening methods often fail. The thread forming design eliminates the need for tapped holes, reducing production steps while creating stronger, more reliable connections. The tri-lobe shank displaces material during installation, forming permanent threads that resist loosening under vibration - a critical advantage in automotive, electronics, and machinery applications. Combined with the Torx Plus drive system, these screws deliver maximum torque transfer without stripping, ensuring consistent clamping force in high-volume manufacturing environments. The zinc-plated steel construction provides essential corrosion resistance while maintaining the strength required for demanding industrial use.

Specification Summary & Compliance

These metric M4 x 0.7mm pitch x 16mm length screws feature ISO-standard coarse threads with Class 2A tolerance and precise length control (-0.8 to 0mm). The fully threaded design with blunt tip and right-hand threading ensures consistent performance across applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global supply chains and environmentally conscious manufacturing operations.
