S-94058A311 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant performance with zinc-plated 410 stainless steel construction for extended service life in harsh environments
• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.187" thickness in stainless steel and sheet metal
• Superior sealing capability through the stainless steel/rubber washer combination that prevents leakage and environmental ingress
• High-torque installation enabled by external hex drive design for secure fastening in demanding applications
• Reliable thread formation through BSD thread forming design that creates strong, permanent threads in parent material
• Full-length threading ensures maximum grip and holding power across the entire 2" fastener length
• Regulatory compliance with RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 12 zinc-plated stainless steel tapping screws deliver exceptional engineering value by combining thread forming technology with integrated sealing capabilities. The BSD thread forming design creates precise, durable threads in stainless steel and sheet metal applications without requiring pre-tapped holes, significantly reducing installation time and labor costs. The zinc-plated 410 stainless steel construction provides superior corrosion resistance, while the stainless steel/rubber sealing washer creates reliable environmental seals that prevent moisture and contaminant ingress. The external hex drive allows for high-torque installation, ensuring secure fastening in demanding industrial applications where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

This No. 12 tapping screw features a 0.216" thread diameter with 14 TPI right-hand threads and full threading along the 2" length. The fastener includes a No. 3 drilling tip capable of penetrating materials up to 0.187" thick without pre-drilling. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The combination of thread forming technology and precision engineering delivers reliable performance in stainless steel and sheet metal applications where corrosion resistance and sealing integrity are paramount.
