S-93406A304 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional Corrosion Resistance: Crafted from 18-8 Stainless Steel, these screws withstand harsh environments, reducing maintenance and replacement costs in industrial settings.
• Superior Holding Power: The wide rounded truss head design distributes clamping force over a larger area, preventing pull-through and ensuring a secure, vibration-resistant fastening in sheet metal.
• Efficient Thread Forming: The A/AB type thread forming technology creates strong, clean threads in pre-drilled holes without generating chips, streamlining assembly and improving joint integrity.
• Optimized for Sheet Metal: Designed specifically for use in sheet metal up to 0.025" thickness, these screws provide reliable fastening with a recommended 3/16" drill bit for precise installation.
• High-Strength Fastening: The fully threaded No. 12 shank with 11 threads per inch ensures maximum engagement and shear strength for demanding applications.
• User-Friendly Installation: The No. 3 Phillips drive offers a common and secure interface for efficient driving with standard tools, reducing installation time.
• Compliant & Reliable: Meets RoHS 3 and REACH regulations, ensuring they are free from hazardous substances and suitable for global industrial supply chains.

Professional Applications & Engineering Value

These 18-8 Stainless Steel Phillips Truss Head Tapping Screws are engineered to solve critical challenges in sheet metal fabrication and assembly. The thread forming (Type A/AB) design eliminates the need for tapping operations, as the screw forms its own mating thread, reducing labor and tooling costs while preventing metal chip contamination. The corrosion-resistant material ensures long-term durability in environments exposed to moisture or chemicals, preventing fastener failure. The wide truss head provides a larger bearing surface, which is crucial for preventing the screw head from pulling through thin sheet metal under load or vibration. This makes them an ideal, high-reliability choice for HVAC systems, electronic enclosures, automotive panels, and other industrial equipment where vibration resistance and structural integrity are paramount.
