Features

Self tapping thread enables direct threading into sheet metal, eliminating the need for pilot holes and enabling rapid, repeatable installations.

Serrated indented hex washer head provides a wide bearing surface and serrations under the head to improve torque transfer and resist loosening under vibration.

Unslotted drive supports secure engagement with compatible tools, reducing cam-out risk during driving and offering a compact drive profile.

Material: 18/8 Stainless Steel yields excellent corrosion resistance in exterior, humid, and coastal environments, increasing long-term service life in harsh conditions.

Hex washer head geometry distributes clamp load over a larger area to minimize sheet metal pull-through in thin gauge applications.

Applications include sheet metal enclosure assembly, HVAC duct fabrication, appliance housings, and automotive body components where fast, reliable self tapping fastening is required.
