Professional Applications & Engineering Value

These No. 10 x 3" stainless steel oval head tapping screws are specifically engineered for demanding sheet metal applications where reliability and corrosion resistance are paramount. The thread forming technology eliminates the need for pre-tapped holes while creating stronger thread engagement through material displacement rather than removal. This A/AB tapping screw type with 18-8 stainless steel construction provides exceptional resistance to oxidation and chemical exposure, making them ideal for HVAC systems, electrical enclosures, automotive components, and industrial machinery. The combination of Phillips No. 2 drive and pointed tip ensures quick, accurate installation with standard tools, reducing assembly time while maintaining consistent clamping force in thin-section materials.

Specification Summary & Compliance

These thread forming tapping screws feature precision 0.19" thread diameter with 12 threads per inch and Class 2A thread tolerances for consistent performance. The oval head design measures 0.362" in diameter with standard profile, requiring No. 21 drill bit (0.159") and 82° countersink angle for proper installation. Manufactured to industry standards for A/AB tapping screw types, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the strictest requirements for industrial use while providing maximum drilling thickness capability of 0.025".
