Features

Self-drilling capability: Drills its own hole into metal, eliminating the need for a pilot hole on compatible sheet and plate thicknesses encountered in industrial assemblies.

Washer head: Integrated washer distributes clamp load across the joint surface, reducing risk of pull-through on thin metals and improving vibration resistance.

Indented hex drive: Provides secure torque transfer with common power tools, reducing head cam-out during installation.

Point Type 3: Optimized geometry for efficient penetration and clean breakout in metal substrates.

Material suitability: Carbon Steel delivers high tensile strength suitable for industrial fastener applications in machinery, enclosures, and structural metal work.

Application landscape: Ideal for metal-to-metal fastening in equipment housings, sheet metal enclosures, HVAC ductwork, electrical panels, and light structural framing.
