S-92879A170 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced Corrosion Resistance: Zinc-plated steel construction provides reliable protection against rust, extending service life in various environments.
• Effortless Installation & Reduced Stripping: Phillips/Square dual-drive head offers versatile tool compatibility and minimizes cam-out for faster, more secure fastening.
• Superior Sealing & Vibration Resistance: Integrated conical washer (aluminum/rubber/steel) creates a tight seal and helps prevent loosening under dynamic loads.
• Optimized Thread Engagement & Material Displacement: Cutting wings and thread-forming design enable smooth insertion in plastics and wood without pre-drilling, reducing assembly time.
• Precise Fastening Control: Partially threaded shank ensures consistent clamping force and prevents over-tightening in sensitive materials.
• Broad Application Compatibility: Low-profile pan head and 2" length with 1 1/4" minimum thread engagement suit a wide range of material thicknesses.
• Regulatory Assurance: Compliant with RoHS 3 and REACH standards, ensuring safety and environmental responsibility in industrial use.

Professional Applications & Engineering Value

This No. 12 zinc-plated steel tapping screw is engineered to address common fastening challenges in plastic and wood assemblies. The thread-forming design with cutting wings eliminates the need for tapped holes, reducing labor and tooling costs while minimizing stress cracking in brittle materials. The aluminum/rubber/steel conical washer provides a critical sealing function, protecting against moisture ingress and compensating for material expansion/contraction. Its partially threaded configuration concentrates holding power where needed, preventing joint failure in vibration-prone applications. The Phillips/Square drive accommodates both manual and automated installation, making it ideal for high-volume production environments requiring reliable, repeatable performance.

Specification Summary & Compliance

This screw features a 0.216" thread diameter with approximately 11 threads per inch and a right-hand thread direction. The partially threaded design has a minimum thread length of 1 1/4" on a 2" overall length. It conforms to standard thread-forming tolerances for inch-series fasteners. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting current environmental regulations for industrial components.
