Structural screws are specifically engineered to carry heavy structural loads. They are heat-treated for superior shear strength and typically require no pre-drilling, making them a faster and stronger alternative to traditional lag bolts.
No, self-drilling wood screws feature a specialized point that functions like a drill bit. This design cuts through the fibers of the wood easily, preventing splitting and saving time during installation.
Hex head wood screws provide a larger surface area for high-torque driver sockets. This reduces slippage (cam-out) and ensures a tight, secure hold when fastening heavy timbers or wooden frames.
While chipboard screws are optimized for low-to-medium density materials like particle board and MDF, they can also be used in solid wood. However, pre-drilling is recommended for hardwoods to avoid cracking the material.
Timber screws are ideal for general heavy timber framing, landscaping, and decking projects. Structural screws should be chosen when precise structural load calculations and building code compliances are required.
