Professional Applications & Engineering Value

This heavy-duty No. 12 zinc-plated steel tapping screw delivers exceptional value in steel and sheet metal applications where reliability is critical. The thread-forming BSD design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs. The integrated steel/rubber sealing washer provides a weather-tight seal that protects against corrosion and environmental contaminants, making it ideal for outdoor equipment, HVAC systems, and metal fabrication. The No. 3 drilling tip with 9/32" length ensures precise penetration in materials up to 0.187" thick, while the external hex drive allows for high-torque installation without stripping. These industrial fasteners maintain structural integrity in vibration-prone environments, offering engineers a comprehensive solution for demanding metal joining applications.

Specification Summary & Compliance

This tapping screw features precise dimensional specifications including 0.216" thread diameter with 14 TPI right-hand threads, 3/4" fully threaded length, and Class 2A thread tolerances for consistent performance. The BSD thread-forming design follows industry-standard tapping screw specifications, while the external hex drive (0.313" width) ensures compatibility with standard industrial tools. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, confirming environmental responsibility and suitability for global industrial applications. The flat washer configuration (0.563" OD) with steel/rubber construction meets standard sealing requirements for metal fastening applications.
