S-90048A323 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for long-lasting performance in demanding industrial environments
• Superior thread-forming capability with A/AB tapping screw design creates permanent, vibration-resistant threads in sheet metal without pre-tapping
• Optimal flush installation featuring 82° countersink angle and flat head profile for smooth, professional finishes in sheet metal assemblies
• Efficient installation process with No. 3 Phillips drive providing secure tool engagement and reduced cam-out during high-torque applications
• Maximum holding power through fully threaded 3" length design ensuring complete engagement across the entire fastener length
• Precision thread engagement with 0.242" diameter and 10 threads per inch delivering reliable, consistent fastening performance
• Reduced assembly time with pointed tip design that self-starts in pre-drilled 5.5mm holes for faster installation cycles

Professional Applications & Engineering Value

These No. 14 x 3" zinc-plated steel tapping screws are specifically engineered for sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming design eliminates the need for tapped holes, creating stronger threads by displacing material rather than removing it, resulting in superior pull-out strength. The Phillips flat head configuration with 82° countersink angle ensures flush mounting in thin gauge materials up to 0.025" thickness, while the fully threaded construction provides maximum engagement across the entire fastener length. Ideal for HVAC systems, electrical enclosures, and metal fabrication projects, these screws deliver reliable performance where traditional fasteners might fail under stress or vibration.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.242" thread diameter and 10 threads per inch, these tapping screws feature right-hand threading and standard flat head profile. The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet stringent industrial safety and environmental standards. Designed for use with 5.5mm drill bits and featuring No. 3 Phillips drive, these fasteners provide consistent performance across production runs while maintaining compliance with international regulatory requirements.
