Features

Self-tapping capability: Inserts threads into metal without pre-drilled pilot holes for thin gauge sheet metal, enabling fast assembly and reduced labor.

Flat head with countersunk profile: Provides flush surface and improved load distribution in panel assemblies.

Phillips drive: Allows reliable torque transfer with standard toolsets; reduces cam-out risk in dense layouts.

Finish: Black oxide offers moderate corrosion resistance and compatibility with lubricants, enhancing drive efficiency.

Material: Steel provides high nominal shear strength and rigidity for general sheet metal fastening tasks.

Use cases: Suitable for mounting enclosure panels, HVAC sheet metal, automotive trim, and appliance housings; compatible with common sheet metal gauges within typical self tapping range.

Installation considerations: For thicker gauges, pre-drill or pilot hole guidance; align parts precisely to ensure consistent thread engagement.
