Professional Applications & Engineering Value

These heavy-duty tapping screws are engineered specifically for challenging stainless steel and sheet metal applications where corrosion resistance and sealing integrity are critical. The zinc-plated 410 stainless steel construction provides exceptional protection against environmental factors, while the thread forming BSD design creates secure, permanent fastenings without requiring pre-tapped holes. The integrated stainless steel/rubber sealing washer solves common leakage and vibration loosening issues in outdoor equipment, HVAC systems, and metal fabrication. With their self-drilling No. 3 tip capable of penetrating up to 0.187" thickness, these external hex drive screws significantly reduce installation time and labor costs in industrial assembly lines and maintenance operations.

Specification Summary & Compliance

These No. 12-14 thread forming tapping screws feature precise 0.216" thread diameter with 14 threads per inch and right-hand threading throughout the 1-1/2" length. Manufactured to BSD screw standards with external hex drive (0.313" head width) and flat washer configuration (0.563" OD). The thread forming tapping method ensures reliable performance in metal substrates, while the zinc-plated 410 stainless steel material and stainless steel/rubber washer comply with industrial corrosion resistance requirements. Products meet relevant industry standards for metal fastening applications and material specifications.
