S-94155A103 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
• Excellent thread-forming capability for secure, vibration-resistant fastening in sheet metal without requiring pre-tapped holes.
• Optimized pan head design with No. 1 square drive provides increased torque transmission and reduced cam-out during installation.
• Fully threaded pointed tip enables quick, self-starting penetration and consistent grip across the entire 5/8" length.
• Precision-engineered dimensions including 0.138" thread diameter and 18 TPI ensure reliable fit and reduced risk of strip-out.
• Comprehensive compliance with RoHS 3 and REACH regulations, guaranteeing safe, environmentally responsible manufacturing.
• Streamlined installation process with compatibility for No. 32 drill bits and 0.025" maximum drilling thickness, saving time and labor costs.

Professional Applications & Engineering Value

This thread forming tapping screw is specifically engineered for demanding sheet metal applications, where traditional fasteners often fail due to vibration loosening or material fatigue. The 18-8 stainless steel composition provides exceptional resistance to rust and chemical exposure, making it ideal for outdoor equipment, HVAC systems, and electronic enclosures. The pan head design with No. 1 square drive offers superior torque transfer, minimizing installation tool slippage and reducing assembly errors. By utilizing a thread forming rather than thread cutting approach, these screws create stronger, more durable threads in the base material without generating chips, eliminating contamination risks in sensitive environments. The fully threaded construction and pointed tip ensure rapid penetration and uniform stress distribution, preventing joint failure in high-vibration industrial settings.

Specification Summary & Compliance

This No. 6-18 x 5/8" tapping screw features precision inch measurements with 0.138" thread diameter and 18 threads per inch, adhering to standard industrial tolerances for consistent performance. The screw follows thread forming (Type A/AB) specifications for sheet metal applications, with compatibility for No. 32 drill bits (0.116" diameter) and 0.025" maximum drilling thickness. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability throughout the supply chain.
