S-90106A556 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments.
• Enhanced drilling efficiency with integrated No. 3 drill tip, allowing for quick penetration in steel, stainless steel, and sheet metal up to 0.21" thickness.
• Eliminates the need for pre-tapping through thread forming technology, reducing installation time and labor costs.
• Secure, vibration-resistant fastening with a flanged hex head design that provides a larger bearing surface and prevents loosening.
• High torque application capability via external hex drive, enabling easy installation with standard tools and minimizing stripping.
• Full-length threading ensures maximum grip and uniform load distribution along the entire 1-1/2" length.
• Compliance with strict environmental standards including RoHS 3 and REACH, making them safe for regulated industries.

Professional Applications & Engineering Value

These 410 Stainless Steel flanged hex head tapping screws are engineered to solve common fastening challenges in metalworking and fabrication. The thread forming design creates strong, precise threads in ductile materials like steel, stainless steel, and sheet metal, eliminating the need for separate tapping operations and reducing assembly time. The integrated No. 3 drill tip and capability to drill up to 0.21" thick materials allow for direct installation without pre-drilling, minimizing hole preparation errors. The flanged head distributes clamp load effectively, reducing the risk of material distortion, while the external hex drive ensures high torque transfer for secure fastening in high-vibration environments such as machinery, automotive assemblies, and structural metal frames.

Specification Summary & Compliance

This 1/4"-14 x 1-1/2" tapping screw features a right-hand thread with approximately 14 threads per inch and is fully threaded for consistent performance. It conforms to standard inch system measurements and is designed for thread forming (BSD type) applications. The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets current environmental and safety standards for industrial use.
