S-90048A317 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments.
• Efficient thread forming creates strong, permanent threads in sheet metal, eliminating the need for pre-tapped holes and speeding up assembly.
• Secure, flush installation with a standard 82° flat head and Phillips drive, providing a clean finish and preventing snagging.
• Maximum material engagement from the fully threaded, pointed tip design ensures exceptional pull-out strength and vibration resistance.
• Reliable dimensional consistency with a No. 14-10 thread size (0.242" diameter, 10 TPI) for predictable performance and interchangeability.
• Compliance with major environmental regulations (RoHS 3 and REACH) ensures safety and suitability for global supply chains.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are precision-engineered for sheet metal applications, where their thread-forming (Type A/AB) design is a critical advantage. By displacing material to form strong internal threads, they eliminate the risk of chip creation common with thread-cutting alternatives, making them ideal for thin-gauge metals and electrical enclosures where debris could cause short circuits. The Phillips flat head with its 82° countersink angle sits flush with the workpiece surface, providing a smooth profile that is essential for aerodynamic housings, machinery panels, and assemblies where protruding fasteners are not permissible. The combination of a fully threaded shank and pointed tip ensures immediate engagement and maximizes clamping force, directly addressing the common industrial challenge of fastener loosening under vibration in HVAC systems, automotive fabrication, and electronic chassis assembly.

Specification Summary & Compliance
