S-94209A550 8-32 x 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black protective coating for extended service life in harsh industrial environments
• Maximum torque transfer and reduced cam-out through Torx Plus IP20 drive system and Tri-Lobe shank design
• Excellent thread-forming capability in aluminum, brass, and copper without requiring pre-tapped holes
• Reliable fastening performance with UNC coarse thread spacing ensuring secure connections in soft materials
• Enhanced driving efficiency with fully threaded design and rounded pan head for flush installation
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for global industrial applications
• Precision dimensional control with length tolerance of -0.03" to 0" ensuring consistent installation results

Professional Applications & Engineering Value

These 8-32 x 3/4" Torx Plus tapping screws deliver exceptional engineering value in aluminum, brass, and copper applications where traditional fastening methods often fail. The black corrosion-resistant coated steel construction provides superior protection against environmental degradation, while the Tri-Lobe shank design significantly reduces cam-out incidents during high-torque installation. The thread forming capability eliminates the need for separate tapping operations in soft metals, streamlining production processes and reducing assembly costs. With UNC coarse thread spacing and Torx Plus drive system, these screws maintain structural integrity in vibration-prone environments, making them ideal for electrical enclosures, machinery components, and metal fabrication where reliable, long-lasting fastening is critical.

Specification Summary & Compliance

These tapping screws feature precision UNC thread form with 8-32 thread size and coarse spacing, manufactured to exacting dimensional standards with length tolerance of -0.03" to 0". The fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial applications. The thread forming design requires No. 29 drill bit (0.136" diameter) for proper installation in aluminum, brass, and copper substrates, providing reliable performance in demanding industrial fastening scenarios.
