S-90935A325 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel construction for extended service life in demanding industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Streamlined installation process using standard No. 3 Phillips drive and 3/16" drill bit for quick, tool-compatible fastening
• Maximum material engagement through fully threaded design that distributes load evenly across the entire fastener length
• Enhanced grip and stability from the pan head design that provides superior clamping force for sheet metal assemblies
• Reliable performance in thin materials with specialized tip geometry optimized for 0.025" maximum drilling thickness applications
• Compliance-ready manufacturing meeting RoHS 3 and REACH environmental standards for global project specifications

Professional Applications & Engineering Value

These black-oxide steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger thread engagement than conventional fasteners. The fully threaded configuration ensures maximum pull-out resistance in thin-gauge materials, preventing loosening under vibration and thermal cycling. The Phillips pan head drive system provides reliable torque transmission without cam-out issues, while the corrosion-resistant black-oxide finish protects against environmental degradation in both indoor and outdoor applications. These A/AB type tapping screws are engineered specifically for demanding industrial environments where fastener reliability directly impacts assembly integrity and product lifespan.
