S-90380A144 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various environments
• Enhanced holding power in plastic materials through TRS thread forming technology that creates strong, permanent threads without chips
• Reduced installation torque and cam-out risk with Phillips No. 2 drive design for efficient, secure fastening
• Excellent pull-out resistance thanks to the tri-lobe shank cross-section that provides superior retention in plastic substrates
• Complete thread engagement with fully threaded design and 19 TPI for maximum fastening strength throughout the entire length
• Streamlined installation process with standard 1/8" drill bit compatibility, eliminating guesswork and reducing assembly time
• Compliance with international environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries

Professional Applications & Engineering Value

These No. 6 x 1/4" zinc-plated steel tapping screws are specifically engineered for plastic applications where traditional fastening methods often fail. The TRS thread forming technology creates durable, high-strength threads in plastic substrates without generating chips or debris that could compromise the assembly. The tri-lobe shank design displaces material during installation, creating exceptional resistance to vibration loosening and pull-out forces. With Phillips No. 2 drive compatibility, these screws provide reliable installation using standard tools while minimizing cam-out incidents. Ideal for industrial assembly, electronics enclosures, automotive plastic components, and construction applications where plastic-to-plastic or plastic-to-metal connections require secure, long-lasting fastening solutions that maintain integrity under stress and environmental exposure.

Specification Summary & Compliance

These thread forming screws feature precise 0.138" thread diameter with 19 threads per inch and 1/4" length for consistent performance. Manufactured to exacting standards with right-hand threading and fully threaded design for maximum engagement. The zinc-plated steel construction provides corrosion protection while maintaining strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory compliance for industrial and commercial applications worldwide.
