S-90048A308 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
• Exceptional holding power through thread forming design that creates stronger, more permanent fastening in sheet metal applications
• Clean, flush installation with undercut flat head and 82° countersink angle that sits perfectly flush with material surfaces
• Optimized for thin materials with maximum drilling thickness of 0.025" for reliable performance in sheet metal fabrication
• Enhanced driving efficiency with No. 3 Phillips drive that provides secure tool engagement and reduces cam-out
• Full-thread engagement along the entire 1/2" length ensures maximum grip and vibration resistance
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These No. 14 zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable fastening in thin materials is critical. The thread forming design eliminates the need for pre-tapped holes, creating stronger threads through material displacement rather than removal. This results in superior vibration resistance and pull-out strength compared to conventional fasteners. The 82° countersink angle combined with the undercut flat head profile ensures a clean, flush finish that prevents snagging and maintains aerodynamic surfaces in HVAC, electronics enclosures, and automotive assemblies. The zinc plating provides essential corrosion protection for industrial environments, while the Phillips drive system offers efficient installation with standard tools. These tapping screws solve common challenges of strip-out and loose fasteners in thin-gauge materials up to 0.025" thickness.

Specification Summary & Compliance

These sheet metal tapping screws feature precision 0.242" thread diameter with 10 threads per inch and fully threaded design for maximum engagement. The flat head with undercut profile and 82° countersink angle ensures proper seating in prepared holes. Manufactured to industry standards for thread forming tapping screws (Type A/AB), these fasteners maintain consistent dimensional accuracy. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and safety in industrial applications worldwide.
