Key Features & Benefits at a Glance

• Superior thread forming capability creates permanent, vibration-resistant threads in sheet metal without requiring pre-tapped holes
• Flanged hex head design provides increased bearing surface for better load distribution and eliminates the need for separate washers
• External hex/slotted drive combination offers versatile installation options with standard tools while preventing cam-out
• Fully threaded pointed tip ensures maximum thread engagement and easier starting in pre-drilled holes
• Precision-engineered dimensions with No. 10-12 thread specification delivers reliable performance in 0.025" maximum thickness materials
• Environmental compliance assurance meets RoHS 3 and REACH standards for safe use in regulated industries
• Optimized drill bit compatibility with No. 21 size (0.159" diameter) ensures proper hole preparation for secure fastening

Professional Applications & Engineering Value

These thread forming tapping screws are specifically engineered for sheet metal applications where reliable fastening is critical. The Type A thread forming design displaces material rather than cutting it, creating stronger threads that resist loosening under vibration - a common challenge in metal fabrication and assembly. The flanged hex head provides excellent clamp load distribution while the fully threaded configuration ensures maximum holding power throughout the entire fastener length. These industrial fasteners are ideal for HVAC systems, electrical enclosures, automotive components, and machinery where vibration resistance and environmental compliance are essential requirements. The combination of external hex drive and slotted head offers installation flexibility in both automated and manual assembly environments.

Specification Summary & Compliance

This No. 10-12 x 1/2" hex head tapping screw features a 0.19" thread diameter with 12 threads per inch right-hand threading and meets standard inch system specifications. The screw is fully threaded with a pointed tip for easy insertion and features a 0.313" hex head width with 0.151" head height. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory compliance for industrial applications worldwide. The specified No. 21 drill bit (0.159" diameter) is recommended for proper hole preparation in materials up to 0.025" maximum drilling thickness.
