S-94155A111 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and long-term reliability.
• Efficient thread forming design creates strong, permanent threads in sheet metal without chips, reducing assembly time and improving joint integrity.
• Secure, high-torque installation enabled by the No. 1 square drive and pan head, minimizing cam-out and ensuring consistent fastening.
• Full 1-1/2" threading provides maximum grip length and load distribution across the entire sheet metal thickness.
• Precise, pointed tip allows for easy alignment and quick starting in pre-drilled No. 32 holes (0.116" diameter).
• Optimized for 0.025" maximum thickness materials, delivering reliable performance in standard sheet metal applications.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global industrial standards.

Professional Applications & Engineering Value

These No. 6-18 thread forming screws are engineered to address common challenges in sheet metal assembly, such as material fatigue and loosening under vibration. The 18-8 stainless steel offers excellent strength and corrosion resistance, while the Type A/AB thread forming design displaces material to form robust, leak-resistant threads without removing metal—eliminating debris and enhancing structural integrity. The pan head with No. 1 square drive ensures reliable torque transmission, reducing installation errors in high-volume production. Ideal for HVAC, automotive, and electronics enclosures, these self-tapping screws streamline workflows by pairing with standard No. 32 drill bits, minimizing tooling costs and assembly time.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.138" and 18 threads per inch, ensuring precise fit in pre-drilled holes. The fully threaded design and pointed tip support consistent performance in sheet metal up to 0.025" thickness. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), these screws meet stringent environmental and safety regulations for industrial use, providing reliable, specification-driven fastening solutions.
