S-94209A140 10-24 x 3/4" 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 drive system (IP25/T25) for faster installation and fewer damaged fasteners
• Exceptional holding power in soft metals thanks to the Tri-Lobe shank design that creates secure, vibration-resistant connections in aluminum, brass, and copper
• Reliable thread forming capability eliminates the need for tapping operations, reducing assembly time and tooling requirements
• Optimized for North American applications with UNC coarse threading (10-24) ensuring compatibility with standard components and fixtures
• Streamlined installation process with precise No. 21 drill bit (0.159") specification for perfect hole preparation
• Environmental compliance assurance meeting RoHS 3 and REACH standards for sustainable manufacturing practices

Professional Applications & Engineering Value

These thread forming tapping screws deliver exceptional engineering value in aluminum, brass, and copper applications where traditional fastening methods often fail. The Tri-Lobe shank cross-section creates permanent, high-retention threads in soft metals without requiring pre-tapped holes, significantly reducing assembly time and labor costs. The zinc-plated steel construction provides reliable corrosion protection in industrial environments, while the Torx Plus drive system ensures maximum torque transmission without stripping, making them ideal for high-volume production lines and automated assembly systems. The 3/4" length and 10-24 UNC coarse thread configuration offer versatile fastening solutions for electrical enclosures, HVAC components, and metal fabrication projects where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

These 10-24 thread forming screws feature UNC coarse threading with standard manufacturing tolerances and fully threaded design for consistent performance. The zinc-plated steel material and Torx Plus drive (IP25/T25) comply with industry standards for drive systems and corrosion protection. Manufacturing and material composition fully adhere to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring compliance with international hazardous substance restrictions and sustainable manufacturing requirements.
