1. Superior Corrosion Resistance: 304 stainless steel contains 18% chromium and 8% nickel, forming a protective oxide layer that resists rust, saltwater, and UV damage—perfect for coastal, marine, or humid environments (unlike zinc-plated screws that corrode within 1–2 years outdoors).

2. High Tensile Strength: Rated at A2-70, these lag screws have a minimum tensile strength of 700 MPa and yield strength of 450 MPa, supporting heavy loads (up to 2,000 lbs per screw in dense wood) for deck joists, fence posts, and roof trusses.

3. Wrench-Driven Installation: The hexagonal head allows for torque application with a socket wrench or spanner, creating a tighter fit than Phillips/slotted head wood screws—reducing the risk of stripping or loosening over time.

4. Splinter-Free Wood Engagement: The sharp, tapered point and coarse threads pull the screw into wood smoothly, minimizing splintering (critical for hardwoods like oak and maple) and ensuring a flush, secure connection.
