Features

Self-tapping performance: Creates its own thread in sheet metal, enabling installation without pre-drilled pilot holes within appropriate sheet thickness range.

Indented Hex Washer Head: Low-profile head provides flush seating and distributes clamping load to resist pull-out under vibration.

Drive compatibility: Slotted drive supports common hand and power tools, simplifying field maintenance and fabrication workflows.

Finish and corrosion resistance: Zinc plating with baked coating offers durable corrosion resistance for indoor and light outdoor applications.

Material and strength: Steel substrate delivers adequate shear and tensile strength for typical sheet metal assemblies.

Practical applications: Suitable for HVAC ductwork, electrical enclosures, automotive body panels, appliance assemblies, and light fabrication where metal-to-metal fastening is required.

Installation considerations: Ensure sheet thickness aligns with Type AB self-tapping specification to maximize thread engagement and minimize stripping.
