S-90925A255 Length 1 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
• Maximum torque transmission through T25 Torx drive design, preventing cam-out and ensuring secure fastening
• Excellent thread-forming capability creates strong, permanent threads in sheet metal up to 0.025" thickness without pre-tapping
• Full-length threading provides consistent holding power along the entire 1-3/4" length for reliable fastening
• Optimized pan head design offers a balance of low profile and sufficient bearing surface for secure sheet metal connections
• Precision pointed tip ensures easy starting and accurate alignment with pre-drilled No. 21 holes (0.159" diameter)
• Environmental compliance meets RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws are engineered specifically for sheet metal applications where reliable fastening is critical. The zinc-plated steel construction provides essential corrosion protection in industrial settings, while the T25 Torx drive delivers superior torque transmission compared to traditional drive systems, reducing tool slippage and improving installation efficiency. The thread forming design creates strong, permanent threads in sheet metal without generating chips, eliminating contamination concerns in sensitive applications. With fully threaded construction and pointed tip, these screws ensure quick starts and consistent performance in materials up to 0.025" thickness, making them ideal for HVAC systems, electrical enclosures, metal fabrication, and industrial equipment assembly where vibration resistance and long-term reliability are paramount.
