Technical Features
- T-30 Torx Drive: The T-30 star drive recess provides increased bit engagement compared to slotted or Phillips drives, reducing cam-out during installation and improving torque transfer.
- Wafer Head Profile: The low-profile wafer head seats flush or near-flush against the work surface, minimizing protrusion and reducing snag points in structural assemblies.
- Treated Lumber Compatible: Manufactured to be compatible with pressure-treated lumber, making these screws suitable for deck framing, fencing, and other exterior structural applications.
- Black Finish: The black coating provides a consistent aesthetic finish suitable for applications where fastener appearance is a consideration.
- Bucket Packaging (25-Count): Packaged in quantities of 25 per bucket for organized jobsite storage and easy inventory management.
Applications
- Structural fastening into treated lumber for decks, fences, and framing
- Wood construction assemblies requiring a low-profile head
- General lag screw applications in dry or standard outdoor environments
Corrosive Environment Notice: These fasteners are not recommended for use in areas within one mile of saltwater, near swimming pools, in environments with exposure to corrosive chemicals, or in livestock confinement areas where elevated corrosion risk is present.
