S-90055A156 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring longevity in demanding industrial environments
• Enhanced driving efficiency with Phillips No. 2 drive, reducing cam-out and tool slippage during installation
• Optimal flush mounting thanks to the standard flat head and 82° countersink angle, providing a smooth finished surface
• Exceptional holding power through thread forming Type B technology, creating strong, permanent threads in sheet metal without pre-tapping
• Full-length threading for maximum grip along the entire 3/4" length, distributing load evenly and preventing material pull-out
• Precision dimensional accuracy with 0.138" thread diameter and 20 threads per inch, ensuring consistent performance and compatibility
• Environmental compliance assurance meeting RoHS 3 standards, making them safe for regulated industrial applications

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and durability are paramount. The thread forming Type B design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs in high-volume manufacturing. The Phillips flat head with 82° countersink sits perfectly flush with surfaces, preventing snagging and maintaining aerodynamic profiles in HVAC systems, electronic enclosures, and automotive panels. The zinc plating provides essential corrosion protection in environments with moisture or chemical exposure, while the fully threaded shank ensures maximum thread engagement for vibration-resistant connections that withstand mechanical stress and thermal cycling.
