S-90064A632 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with self-drilling tip that penetrates up to 0.21" thickness in steel and sheet metal
• Superior corrosion resistance through zinc-plated steel construction for extended service life in demanding environments
• Enhanced load distribution with 0.52" flange diameter that prevents pull-through and reduces surface damage
• High-torque installation capability through external hex drive design with 3/8" head width for secure fastening
• Permanent thread engagement achieved through thread-forming BSD design that creates strong, vibration-resistant connections
• Maximum material contact with fully threaded 2" length for superior holding power across the entire fastener
• Streamlined inventory management with standardized 1/4"-14 thread pattern compatible with industry specifications

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in industrial fastening applications where time efficiency and connection reliability are paramount. The combination of thread-forming BSD technology and self-drilling No. 3 tip eliminates multiple installation steps, significantly reducing labor costs in steel and sheet metal assembly operations. The flanged hex head design provides superior clamp force while preventing material deformation, making these fully threaded screws ideal for structural applications requiring vibration resistance. The external hex drive ensures compatibility with standard industrial tools while accommodating high torque requirements. Engineered for heavy-duty fastening in manufacturing, construction, and metal fabrication, these screws maintain integrity in challenging environments thanks to their corrosion-resistant zinc plating.

Specification Summary & Compliance

These 1/4"-14 tapping screws feature precision right-hand threads with industry-standard thread form and Class 2A thread tolerances for consistent performance. The BSD (British Standard Drilling) thread-forming design ensures reliable engagement in base materials without requiring tapped holes. Manufactured to meet applicable industrial standards for tapping screws, these fasteners comply with RoHS and REACH environmental directives. The 2" length with fully threaded configuration and 0.25" thread diameter provides optimal fastening capability for a wide range of material thicknesses in steel and sheet metal applications.
