Features

Self-tapping design: Forms its own thread in thin-gauge sheet metal, enabling rapid assembly without pre-drilling.

Indented Hex Washer Head: Provides a low-profile, flush seating surface with even clamp load distribution and reduced protrusion in tight assemblies.

Drive compatibility: Unslotted drive supports standard hex driver tooling, reducing tool slip and improving installation consistency in production environments.

Corrosion resistance: Zinc plating with baked finish offers durable protection for indoor and light outdoor applications where metal fasteners are exposed to moisture and environmental contaminants.

Applications: Suitable for automotive interior panels, appliance enclosures, electrical housings, HVAC sheet metal assemblies, and general metal fabrication tasks requiring reliable sheet metal fastening.

Material: Steel construction provides adequate tensile strength for common sheet metal fastening scenarios while maintaining workable hardness for self-tapping operation.
