S-90048A290 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient thread forming technology creates stronger, more secure fastenings in sheet metal without requiring pre-tapped holes
• Optimized 82° countersink angle ensures flush mounting and prevents snagging in finished applications
• Full threading with pointed tip provides maximum grip length and easier starting in sheet metal substrates
• Phillips drive with No. 3 size delivers reliable torque transfer and reduces cam-out during installation
• Undercut flat head design allows for deeper seating and cleaner finished appearance in metal assemblies
• Precise dimensional compatibility with standard 3/16" drill bits simplifies installation and reduces preparation time

Professional Applications & Engineering Value

These No. 12 tapping screws are specifically engineered for sheet metal applications where reliability and installation efficiency are critical. The thread forming design eliminates the need for pre-tapped holes, creating stronger threads directly in the base material through cold forming. This results in superior vibration resistance and reduced loosening in dynamic applications. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the flat undercut head with 82° countersink ensures clean, flush installations in metal fabrication, HVAC systems, and electronic enclosures. The combination of Phillips drive and precise threading specifications makes these A/AB tapping screws ideal for high-volume assembly operations requiring consistent performance.

Specification Summary & Compliance

These industrial fasteners feature precise dimensional specifications including 0.216" thread diameter, 11 threads per inch, and 1/2" length with full threading. Manufactured to A/AB tapping screw standards with right-hand thread direction and round shank cross-section. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The undercut flat head profile and pointed tip design meet industry standards for sheet metal fastening applications.
