Recommended Applications

These screws are built for high‑strength structural uses where traditional lag screws would typically be installed:

• Deck Framing & Ledgers: Excellent for high‑load deck‑to‑structure connections thanks to robust shear and pull‑out capability.
• General Wood Framing: Suitable for studs, beams, headers, trusses, and structural assemblies.
• Outdoor Structures: Pergolas, gazebos, fencing, elevated platforms, and heavy timber projects benefit from corrosion‑resistant coating.
• Engineered Lumber: Appropriate for LVL, LSL, and other engineered structural wood materials.
• Structural Renovation & Reinforcement: Ideal for retrofitting framing members and adding structural support in remodels.
• Lag Screw Replacement: Designed to outperform and install faster than standard lag bolts, often eliminating pre‑drilling.
