S-94425A790 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
• High-strength, secure fastening achieved through thread forming design, creating durable threads in steel and sheet metal without pre-tapping.
• Enhanced torque transmission and reduced cam-out with the T27 external hex/torx drive, allowing for reliable installation with standard tools.
• Efficient self-drilling capability with the specialized No. 3 drill tip, penetrating up to 0.187" thick materials to speed up assembly and reduce labor.
• Vibration-resistant locking provided by serrations under the head, maintaining clamp load and preventing loosening in dynamic applications.
• Increased stability and load distribution from the 0.445" flange diameter, minimizing surface damage and improving joint integrity.
• Consistent, full-length engagement with fully threaded shank and 14 TPI, ensuring uniform grip and reliable performance across the entire fastener length.

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws are engineered to address common challenges in steel and sheet metal fabrication, such as material fatigue and installation inefficiency. The thread forming design eliminates the need for separate tapping operations, reducing assembly time and tooling costs while forming strong, clean threads that resist stripping. The combination of a T27 external hex/torx drive and self-drilling tip allows for quick, one-step installation in materials up to 0.187" thick, making them ideal for HVAC, automotive, and construction applications where speed and reliability are critical. The flanged design and serrated locking further enhance vibration resistance, ensuring secure fastening in high-stress environments.
