S-94209A687 M4 x 20 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced torque transmission and reduced cam-out with Torx Plus IP20/T20 drive system for reliable, high-torque installations
• Excellent thread-forming capability in aluminum, brass, and copper materials through tri-lobe shank design that displaces material without chip formation
• Optimized for quick assembly with coarse 0.7mm thread pitch providing faster installation in soft materials
• Maximum thread engagement through fully threaded design ensuring superior holding power across the entire fastener length
• Precise length control with -0.8 to 0mm tolerance for consistent performance in automated assembly applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

These M4 metric tapping screws are specifically engineered for thread forming applications in non-ferrous materials including aluminum, brass, and copper. The tri-lobe shank design creates strong, permanent threads by displacing material rather than cutting, eliminating chip-related contamination in sensitive assemblies. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength for durable fastening in electrical enclosures, machinery components, and automotive assemblies. The Torx Plus drive system delivers exceptional torque transmission, reducing tool slippage and fastener damage during high-volume production. This combination of features addresses critical industrial challenges including vibration resistance, material compatibility, and assembly efficiency in manufacturing environments.

Specification Summary & Compliance
