Professional Applications & Engineering Value
These 316 stainless steel tapping screws are specifically engineered for demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates the need for pre-tapped holes, creating strong, permanent threads that resist vibration loosening and maintain clamping force under stress. The Phillips drive system with No. 3 size ensures efficient installation while the fully threaded design provides consistent engagement throughout the material thickness. Ideal for HVAC systems, electronic enclosures, and industrial equipment where corrosion resistant fasteners must withstand environmental exposure while maintaining secure connections in thin gauge materials.
Specification Summary & Compliance
This No. 12 sheet metal screw features precise inch measurements with 0.216" thread diameter and 11 threads per inch in right-hand orientation. The thread forming tapping method (Type A/AB) and fully threaded configuration ensure reliable performance in sheet metal up to 0.025" thickness. Manufactured to industry standards with RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, meeting the latest environmental and safety regulations for industrial fasteners.
