S-90190A299 Length 1 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 capability creates permanent, vibration-resistant threads in sheet metal without requiring pre-tapped holes
• Optimized for sheet metal applications with pointed tip and fully threaded design for smooth penetration and maximum holding power
• Reliable Phillips drive system (No. 3 size) provides secure tool engagement and consistent torque transfer during installation
• Streamlined installation process requiring only a 3/16" drill bit, reducing preparation time and tooling requirements
• Pan head design offers low-profile fastening with good bearing surface for secure component attachment
• Comprehensive regulatory compliance with RoHS 3 and REACH standards ensures environmental responsibility and global market acceptance

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The thread forming design (Type A/AB) displaces material rather than removing it, creating stronger threads with improved resistance to vibration loosening. The fully threaded configuration ensures maximum engagement along the entire fastener length, while the 0.216" thread diameter with 11 threads per inch provides optimal balance between installation speed and holding strength. The combination of Phillips drive and pan head design facilitates efficient installation in confined spaces, making these sheet metal screws ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment where reliable fastening is critical.

Specification Summary & Compliance

This No. 12 x 1-1/2" tapping screw features inch system measurements with Class 2A thread tolerances for consistent performance. The fastener meets industry-standard thread forming specifications for sheet metal applications and is engineered for use with a 3/16" drill bit (0.1875" diameter) for 0.025" maximum drilling thickness. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmentally responsible manufacturing and unrestricted use across global markets.
