Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
- Maximum torque transfer and reduced cam-out through No. 2 square drive design for efficient installation
- Eliminates need for separate washers with integrated flange design, saving assembly time and reducing component count
- Self-tapping thread forming action creates strong, permanent threads in sheet metal without pre-tapping
- Full threading along 1" length provides consistent holding power throughout the entire engagement area
- Pointed tip design enables easy starting and precise alignment in sheet metal applications
- Compliance with RoHS 3 and REACH regulations ensures environmental responsibility and global market acceptance
Professional Applications & Engineering Value
These No. 10-12 zinc-plated steel flanged tapping screws deliver exceptional performance in sheet metal assembly applications where vibration resistance and structural integrity are critical. The thread-forming A/AB tapping screw design creates precise, durable threads in materials up to 0.025" thickness, eliminating the need for separate tapping operations and reducing production time. The flanged pan head with No. 2 square drive provides superior clamping force distribution while preventing screw head sinking into softer materials. Engineered for industrial durability, these fully threaded screws maintain consistent performance in HVAC systems, electrical enclosures, and metal fabrication where reliable fastening is essential for long-term structural stability.
Specification Summary & Compliance
Precision-engineered with 0.19" thread diameter and 12 threads per inch for optimal grip in sheet metal applications. Features Class 2A thread tolerances ensuring consistent performance and interchangeability. Manufactured to industry standards for A/AB tapping screw types with 0.423" flange diameter for enhanced load distribution. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting global compliance requirements for industrial fastener applications.
