Professional Applications & Engineering Value
These Black-Oxide Steel thread forming screws are engineered specifically for sheet metal applications where reliability and installation efficiency are critical. The A/AB tapping screw type with pointed tip and thread forming technology eliminates the need for separate tapping operations, reducing assembly time and labor costs. The oval head profile with standard 82° countersink angle provides a clean, finished appearance while the Phillips No. 2 drive ensures consistent torque transmission. Ideal for HVAC systems, electronic enclosures, and automotive panels, these screws maintain integrity in materials up to 0.025" thickness, preventing strip-out and ensuring long-term joint security in vibration-prone environments.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.164" thread diameter and 15 threads per inch configuration. Features fully threaded design with standard oval head profile and compatible with No. 29 drill bit (0.136" diameter) for optimal performance. These thread forming tapping screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets while maintaining consistent quality and reliability in sheet metal fastening applications.
