S-90066A319 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in humid or demanding industrial environments.
• High-torque installation capability thanks to the external hex drive and 3/8" hex head, allowing for secure fastening with standard tools.
• Reliable thread-forming performance in sheet metal, creating strong, vibration-resistant threads without pre-tapping for faster assembly.
• Integrated steel/rubber flat washer distributes load evenly and provides a sealed, loosening-resistant connection under dynamic loads.
• Full threading and pointed tip ensure quick starts and maximum grip along the entire 2" length for consistent holding power.
• Precise fit and reduced preparation time with recommended 5.5mm (0.2165") drill bit, ensuring optimal thread engagement in materials up to 0.025" thick.
• Compliance with environmental standards including RoHS 3, making them suitable for regulated industries and global supply chains.

Professional Applications & Engineering Value

These No. 14 x 2" zinc-plated steel hex washer tapping screws are engineered to address common challenges in sheet metal fabrication, such as strip-out, vibration loosening, and corrosion. The thread-forming A/AB type design displaces material to create durable internal threads, eliminating the need for separate nuts or tapped holes—reducing assembly steps and labor costs. The combination of a fully threaded shank and integrated steel/rubber washer ensures uniform stress distribution and a weather-resistant seal, ideal for HVAC, electrical enclosures, and automotive panels. With 10 threads per inch and a right-hand thread direction, they provide rapid installation and reliable performance in high-vibration settings, enhancing productivity and joint integrity.

Specification Summary & Compliance

This screw meets standard thread forming specifications for sheet metal applications, with a thread diameter of 0.242" and Class 2A inch-series tolerances. It conforms to RoHS 3 (2015/863/EU) compliance, ensuring it is free of restricted hazardous substances. The external hex drive and flat washer are designed for use with common industrial fastening tools, supporting efficient, repeatable installations in compliance with general industry standards for mechanical fasteners.
