Professional Applications & Engineering Value

These No. 12 x 2" zinc-plated steel tapping screws deliver exceptional performance in sheet metal applications where traditional fastening methods fall short. The A/AB thread forming technology eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating stronger, vibration-resistant connections. The zinc-plated steel construction provides reliable corrosion protection in industrial environments, extending service life and reducing maintenance requirements. With their Phillips/Slotted drive combination, these screws offer installation flexibility across various production scenarios, from assembly lines to field repairs. The fully threaded design ensures maximum holding power across the entire fastener length, making them ideal for joining multiple layers of sheet metal or attaching components to metal frames.

Specification Summary & Compliance

These tapping screws feature precise 0.216" thread diameter with 11 threads per inch and Class 2A thread tolerances for consistent performance. The thread forming tapping method follows industry-standard A/AB specifications for sheet metal applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial and commercial applications worldwide. The 2" length and standard pan head design provide optimal fastening capabilities for sheet metal thicknesses up to the specified maximum drilling capacity.
