Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh environments.
- Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time.
- Optimized for sheet metal up to 0.025" thickness with precise No. 21 drill bit compatibility for clean, secure fastening.
- Enhanced torque transmission via Phillips No. 2 drive, minimizing cam-out and improving installation efficiency.
- Maximum holding power from fully threaded shank, providing consistent grip along the entire length in metal applications.
- Standard pan head profile offers a balanced combination of low profile and good bearing surface for various assemblies.
- Compliance with RoHS 3 and REACH regulations ensures safe, environmentally responsible use in industrial settings.
Professional Applications & Engineering Value
These 18-8 Stainless Steel tapping screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion-induced failure. The thread forming (Type A/AB) design displaces metal rather than cutting it, resulting in stronger thread engagement and reduced risk of loosening under vibration. With a fully threaded No. 10-12 configuration and pointed tip, they penetrate smoothly into pre-drilled holes (using No. 21 drill bit), making them ideal for assembling HVAC systems, electrical enclosures, and automotive panels. The corrosion-resistant properties eliminate the need for additional coatings, lowering lifecycle costs in demanding industrial environments.
Specification Summary & Compliance
This screw features a No. 10-12 thread with right-hand direction and Class 2A inch-series tolerances for consistent fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances. Manufactured to standard tapping screw specifications for Type A/AB, it ensures reliable performance in sheet metal applications with a maximum drilling thickness of 0.025".
