Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws deliver critical solutions for sheet metal fabrication where material integrity and joint reliability are paramount. The thread forming design eliminates the need for pre-tapped holes, reducing labor costs while creating stronger, strip-resistant threads in ductile metals. The 82° countersink angle and flat head profile ensure seamless flush mounting in HVAC systems, electronic enclosures, and automotive panels, preventing surface protrusions that could compromise safety or aesthetics. Manufactured from zinc-plated steel, these A/AB type tapping screws provide excellent resistance to environmental exposure, making them ideal for both indoor and outdoor industrial applications where corrosion protection is essential for long-term performance.

Specification Summary & Compliance

Precision-engineered with 0.216" thread diameter and 11 threads per inch in right-hand direction, these 1 1/4" fully threaded screws maintain consistent Class 2A thread tolerances for reliable engagement. The standard flat head configuration with No. 3 Phillips drive ensures compatibility with common industrial tools. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and restricted substance adherence for global industrial use.
