S-90064A581 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
• Exceptional holding power due to the integrated flange design, which distributes load evenly and eliminates the need for separate washers.
• High-efficiency installation with the external hex drive, providing excellent torque transmission and reducing the risk of tool slippage.
• Self-tapping capability through the drilling tip and thread forming design, allowing for direct use in steel and sheet metal without pre-drilling.
• Reliable thread engagement with fully threaded 14 TPI right-hand threads, ensuring consistent fastening strength across the entire 1" length.
• Optimized for heavy-duty applications in materials up to 0.187" thick, making it ideal for sheet metal fabrication and steel assemblies.
• Broad compatibility with standard BSD tapping screw specifications, ensuring interchangeability and ease of sourcing.

Professional Applications & Engineering Value

Engineered for steel and sheet metal applications, these No. 12 zinc-plated steel tapping screws address common industrial challenges such as time-consuming pre-drilling and inconsistent thread hold. The thread forming technology creates strong, precise threads in the base material, reducing the risk of stripping and enhancing joint integrity. Combined with the drilling tip, this design allows for faster assembly cycles and lower labor costs. The flanged hex head provides a larger bearing surface, which helps prevent pull-through in thin materials and improves vibration resistance. These features make the screw an optimal choice for HVAC systems, automotive panels, and machinery enclosures where reliability and efficiency are critical.
