• Reliable drive performance with No. 2 Phillips head providing secure tool engagement and reduced cam-out risk
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing
• Precision engineering with consistent 12 threads per inch and 0.19" thread diameter for reliable performance in materials up to 0.025" thickness

Professional Applications & Engineering Value

These 316 stainless steel Phillips flat head tapping screws are engineered specifically for demanding sheet metal applications where corrosion resistance and installation efficiency are critical. The thread forming technology eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that won't loosen under stress. The A/AB screw type with pointed tip and right-hand threading ensures quick starts and smooth penetration into pre-drilled holes. The flat head design with standard profile sits flush with surfaces, preventing snagging while providing a clean, professional appearance. Ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment where corrosion resistant screws must maintain integrity in challenging environments while meeting strict regulatory requirements.

Specification Summary & Compliance

These No. 10-12 x 3" tapping screws feature precision thread forming with 12 threads per inch and 0.19" thread diameter, designed for use with No. 21 drill bits (0.159" diameter) and 82° countersink angles. The fully threaded configuration with right-hand direction and round shank cross-section ensures consistent performance in materials up to 0.025" thickness. Manufactured to industry standards for A/AB screw types, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, providing assurance of material safety and regulatory adherence for industrial applications.
