S-90286A298 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced Sheet Metal Grip – Thread forming design creates strong, permanent threads in sheet metal without chips, ensuring reliable fastening in 0.025" maximum thickness materials.
• Quick and Secure Installation – External hex/slotted drive allows for high-torque application with standard tools, reducing assembly time and preventing stripping.
• Superior Load Distribution – Integrated flange spreads clamping force evenly, minimizing surface damage and improving joint integrity under vibration.
• Precision Thread Engagement – Fully threaded No. 12-11 right-hand configuration with pointed tip ensures smooth, self-starting penetration for consistent performance.
• Durable and Corrosion-Resistant – Manufactured to exacting standards, these screws maintain strength and reliability in demanding industrial environments.
• Streamlined Drilling Process – Compatible with 3/16" drill bits (0.1875" diameter), enabling precise hole preparation and reducing setup complexity.
• Environmentally Responsible Compliance – Meets RoHS 3 and REACH regulations, ensuring safe use in global supply chains without hazardous substances.

Professional Applications & Engineering Value

These No. 12-11 thread forming tapping screws are engineered specifically for sheet metal applications where vibration resistance and material integrity are critical. The thread forming (Type A) design displaces material rather than cutting it, creating zero chips and stronger threads that won’t loosen under stress. With a fully threaded shank and pointed tip, installation is fast and accurate, reducing the risk of cross-threading. The external hex/slotted drive offers dual tool compatibility, ideal for both automated and manual assembly lines. The flanged head increases bearing surface, preventing pull-through in thin-gauge metals up to 0.025" thickness. Built for durability and RoHS/REACH compliance, these screws deliver long-term reliability in HVAC, electronics enclosures, and automotive assemblies.

Specification Summary & Compliance

This No. 12 tapping screw features a 0.216" thread diameter with 11 threads per inch and a 1-1/4" length. It includes a hex head (0.313" width, 0.194" height) and 0.432" flange diameter for secure fastening. Manufactured as a Type A thread forming screw with right-hand threading and pointed tip, it is designed for use with a 3/16" drill bit. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safety and regulatory adherence in industrial applications.
