Technical Features
- Black Coating, Approved for Treated Lumber: The black finish is rated for use with chemically treated lumber, preventing coating degradation from preservative compounds while delivering a bold, uniform appearance in exposed structural connections.
- Fast Bite Tip: The engineered tip geometry initiates thread engagement immediately upon contact, reducing drive time and eliminating the need for pre-drilling in typical structural applications.
- Washer Head Design: The integrated washer head distributes clamping load across a broader bearing surface, increasing pull-through resistance and overall joint integrity.
- Star Drive Head: The star drive recess maximizes driver-to-fastener contact, virtually eliminating cam-out and stripping under high-torque installation — particularly critical in structural assemblies where fastener head damage is unacceptable.
Applications
- Outdoor deck framing and decking board attachment
- Structural connections in treated lumber assemblies
- Exterior wood construction where a finished black appearance is specified
- Applications requiring approved fasteners for ACQ, CA, or similarly treated wood products
