S-90048A316 Length 1 1/4" 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 technology creates strong, permanent threads in sheet metal without pre-tapping requirements
• Optimal flush installation with standard 82° flat head profile and Phillips No. 3 drive for clean, professional finishes
• Enhanced grip strength through fully threaded design with 10 threads per inch for maximum holding power in thin materials
• Precision compatibility with 0.2165" drill bits and 0.025" maximum drilling thickness for consistent performance in sheet metal applications
• Reliable drive engagement with Phillips drive system preventing cam-out and ensuring secure installation
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

These No. 14 Phillips flat head tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength. The thread forming Type A/AB design eliminates the need for separate tapping operations, reducing installation time and labor costs. The 82° countersink angle ensures flush mounting in thin gauge materials, preventing protrusions that could compromise product aesthetics or functionality. With fully threaded configuration and 0.242" thread diameter, these screws distribute clamping force evenly, resisting vibration loosening in HVAC systems, electrical enclosures, and automotive components where reliable sheet metal fastening is critical.

Specification Summary & Compliance

These tapping screws feature precise Class 2A thread tolerances with 10 threads per inch and right-hand threading. Manufacturing follows industry standards for Type A/AB thread forming screws with standard flat head profile and pointed tip for easy starting. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance control.
