S-90054A301 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Enhanced torque transmission through external hex/slotted drive design, preventing tool slippage during installation
• Efficient thread forming capability creates permanent, vibration-resistant threads in sheet metal without pre-tapping
• Integrated flange design provides wider bearing surface, distributing clamp load and eliminating need for separate washers
• Full threading along 2" length ensures maximum grip range and consistent holding power throughout engagement
• Precision-engineered No. 12-11 thread configuration delivers optimal pitch for secure fastening in thin sheet metal applications
• Compliance with international environmental standards including RoHS 3 and REACH for global manufacturing compatibility

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are specifically engineered for sheet metal applications where reliable fastening in thin materials is critical. The thread forming design displaces material rather than removing it, creating stronger threads that resist vibration loosening and maintain integrity under stress cycles. The combination of external hex/slotted drive provides dual installation options for both power and manual tools, while the flanged head eliminates washer requirements and reduces assembly time. With precise compatibility for 3/16" drill bits and 0.025" maximum drilling thickness, these A/AB type tapping screws deliver consistent performance in HVAC systems, electronic enclosures, automotive panels, and industrial equipment where material thickness variations demand reliable fastening solutions.

Specification Summary & Compliance

This No. 12-11 tapping screw features a 0.216" thread diameter with 11 threads per inch in right-hand direction, manufactured to standard thread forming specifications for sheet metal applications. The 2" length with full threading and pointed tip ensures easy starting and complete penetration. All dimensions maintain industrial standard tolerances for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental standards for hazardous substance restrictions.
