Technical Features
- W-Cut Self-Tapping Thread Design: Specially engineered thread geometry cuts its own path during installation, reducing drive torque and eliminating the need for pre-drilling in most structural lumber applications.
- Zip-Tip Point: Sharp, hardened tip initiates penetration quickly and cleanly, improving installation speed and reducing wood splitting at entry.
- Patented Climatek (Climacoat) Coating: Factory-applied corrosion-resistant finish rated for both interior and exterior exposure, making these screws suitable for outdoor structural assemblies including decks and ledger boards.
- Washer Head Design: Integrated washer-style head distributes clamping load over a wider surface area, providing superior bearing strength against the fastened material compared to a standard flat head.
- Star Drive (T-25): Six-point star recess provides positive bit engagement, reducing cam-out during high-torque driving and improving installation control.
- Lag Screw Alternative: Classified by GRK as a structural lag screw alternative, allowing use in load-bearing connections where traditional lag screws would otherwise be required.
- T-25 Driver Bit Included: Each 50-pack clamshell includes a compatible T-25 driver bit, enabling immediate use without sourcing a separate accessory.
- Hardened Steel Construction: Specially hardened steel composition supports the structural shear and withdrawal loads associated with beams, posts, and rail connections.

- Carrying beams and structural lumber connections
