Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and durability are critical. The thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs in industrial manufacturing. The zinc-plated steel construction provides excellent corrosion protection, making these flanged screws ideal for HVAC systems, electrical enclosures, automotive components, and metal fabrication projects. The combination of external hex/slotted drive offers flexibility for both power and manual tool applications, while the pointed tip ensures quick starting and proper alignment. These industrial-grade fasteners maintain consistent performance even in high-vibration environments, preventing loosening and maintaining structural integrity.

Specification Summary & Compliance

These tapping screws feature precise Class 2A thread tolerances with a 0.216" thread diameter and 11 threads per inch. The 3/4" length and fully threaded design provide maximum engagement in materials up to 0.025" thickness. Manufactured to industry standards for thread forming screws (Type A/AB), these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial applications worldwide.
