S-94209A470 2-56 x 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-coated steel for extended service life in demanding environments
• Superior torque transmission via Torx Plus IP7 drive, minimizing cam-out and tool wear
• Reliable thread-forming performance in aluminum, brass, and copper without pre-tapped holes
• Optimized Tri-Lobe shank design reduces driving torque while maintaining high strip-out resistance
• Full threading along 5/8" length ensures maximum grip and uniform stress distribution
• Coarse UNC 2-56 thread profile provides rapid installation and vibration resistance
• Precision-matched No. 48 drill bit compatibility for streamlined assembly processes

Professional Applications & Engineering Value

These Tri-Lobe thread forming screws deliver exceptional value in non-ferrous metal assemblies where traditional fastening methods fall short. The black corrosion-resistant coating protects against environmental degradation in electrical enclosures, HVAC components, and marine hardware. Engineered with Torx Plus IP7 drive technology, they eliminate slippage during high-torque installation in automated production lines. The thread forming design creates stronger, more precise threads in aluminum, brass, and copper substrates without generating chips, making them ideal for sealed electronic housings and precision instrumentation where contamination must be avoided. The coarse UNC 2-56 thread maintains holding power in soft materials while reducing installation time.

Specification Summary & Compliance
