Professional Applications & Engineering Value
These black oxide stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and thread integrity are critical. The 18-8 stainless steel construction provides exceptional durability against moisture and chemicals, while the thread forming design (A/AB type) creates strong, permanent threads in sheet metal up to 0.025" thickness without requiring pre-tapped holes. The fully threaded configuration ensures maximum engagement throughout the material thickness, preventing loosening under vibration. The Phillips drive system offers reliable installation with standard tools, making these screws ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment where corrosion-resistant fastening solutions are essential for long-term performance.
Specification Summary & Compliance
This No. 14 x 1-1/4" tapping screw features precision thread forming technology with 0.242" thread diameter and 10 threads per inch, manufactured to industry standards for sheet metal fastening applications. The screw meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance. The black oxide surface treatment on 18-8 stainless steel provides enhanced corrosion protection while maintaining the material's inherent strength characteristics.
