S-90395A242 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
• Efficient thread forming design creates strong, permanent threads in sheet metal without chip removal, reducing installation time
• Secure square drive system (No. 2 size) prevents cam-out and provides positive torque transmission during installation
• Optimized pan head profile offers excellent bearing surface and low-profile appearance for flush mounting applications
• Precision-engineered dimensions with 0.19" thread diameter and 12 TPI ensure consistent performance and reliable connections
• Maximum material compatibility with 0.025" drilling thickness capability for versatile sheet metal applications
• Full regulatory compliance with RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming design (A/AB type) eliminates the need for pre-tapped holes while creating stronger, more vibration-resistant connections compared to traditional fastening methods. The combination of fully threaded construction and pointed tip ensures rapid startup and smooth penetration through sheet materials up to 0.025" thickness. The pan head with square drive provides superior torque transmission while maintaining a low-profile appearance, making these No. 10-12 thread screws ideal for HVAC systems, electrical enclosures, automotive components, and industrial equipment where reliable, corrosion-resistant fastening is critical.

Specification Summary & Compliance

These tapping screws feature precision right-hand threads with 0.19" diameter and 12 threads per inch, manufactured to industry standards for consistent performance. The thread forming tapping method ensures secure fastening in sheet metal applications when used with recommended No. 21 drill bits (0.159" diameter). All components are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmentally responsible manufacturing and material safety standards for global industrial applications.
