Features

Self tapping capability enables formation of internal threads in sheet metal during installation, eliminating pre-drilling for many gauge ranges.

Phillips drive provides high torque transfer with reduced cam-out when paired with proper bit and driving speed.

Flat undercut head yields a flush profile, reducing protrusion on thin metal panels and improving edge clearance.

Finish: Zinc plated with bake coating enhances corrosion resistance in standard service environments for indoor applications.

Material: Steel provides strength and compatibility with common sheet metal thicknesses encountered in enclosures, ductwork, and automotive trims.

Use cases: Ideal for attaching brackets, enclosures, panels, trim, and fastener assemblies in electrical, HVAC, automotive, and appliance applications where a low-profile, secure fastener is required.
