Grade 2 lag screws are economical and easy to drive, often used in light-duty framing, cabinetry support, or interior blocking where vibration and stress are minimal. Simple, consistent, and readily available in a wide range of sizes.
Grade 5
Heat-treated for higher strength and better torque Resistant, Grade 5 lag screws are used when fastening into dense wood, heavy framing, or composite materials that require tighter clamping force. These screws are common in deck framing, structural blocking, and machinery installation where load paths or pullout strength are a concern.
