Powerlags 5/16 In. X 4 In. L Washer High Corrosion Resistant Carbon Steel Lag Screw 1 Pk

SPAX PowerLags are heavy-duty lag screws designed for demanding construction and outdoor applications where strength and corrosion resistance are essential. These washer head lag screws combine robust carbon steel construction with a corrosion-resistant coating, making them ideal for projects exposed to moisture and weathering. Whether you're building decks, framing structures, or securing heavy loads, these fasteners deliver reliable performance and long-lasting durability.

The washer head design distributes load across a wider bearing surface, minimizing the risk of pull-through and reducing material damage during installation. With T-40 drive compatibility that allows for efficient torque transfer, installation is quick and controlled with compatible bits. Finished with a corrosion-resistant coating, these carbon steel screws resist rust and oxidation in wet and outdoor environments.

Features and Benefits

• Corrosion-Resistant Coating: Protects against rust and oxidation, extending the life of your installations in wet, outdoor, or high-moisture environments.
• Washer Head Design: Provides a larger bearing surface that distributes load evenly and reduces the chance of fastener pull-through into softer materials.
• Heavy-Duty Carbon Steel: Delivers the strength needed for structural applications, decking, framing, and securing heavy components.
• T-40 Drive Compatibility: Enables efficient torque transfer during fastening with T-40 compatible bits for quick and controlled installation.
• Versatile Size: The 5/16-inch diameter and 4-inch length suits a wide range of applications from residential to professional construction.
