S-90190A310 Length 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
• Excellent thread-forming capability creates strong, permanent threads in sheet metal without pre-tapping requirements
• Optimized holding power with 10 threads per inch design for maximum grip and vibration resistance in metal assemblies
• Enhanced drive engagement through Phillips No. 3 drive system prevents cam-out and ensures secure installation
• Versatile pan head design provides a standard profile with good bearing surface for reliable clamping force distribution
• Full threading along 1/2" length delivers consistent fastening strength throughout the entire engagement area
• Regulatory compliance assurance meets RoHS 3 and REACH standards for safe, environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 14 zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable fastening is critical. The thread-forming design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs in metalworking and manufacturing processes. The A/AB screw type with pointed tip ensures easy starting and smooth thread formation in materials up to 0.025" thickness. The combination of zinc-plated corrosion protection and fully threaded shank provides exceptional resistance to vibration loosening and environmental degradation, making these industrial fasteners ideal for HVAC systems, electrical enclosures, automotive components, and machinery assemblies where long-term reliability is paramount.

Specification Summary & Compliance

These tapping screws feature precise 0.242" thread diameter with 10 threads per inch and 1/2" length in Class 2A thread tolerance. The pan head style measures 0.476" diameter with standard rounded profile, paired with Phillips No. 3 drive for compatible tooling. Manufactured to A/AB thread-forming screw standards with fully threaded round shank configuration. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
