Deck screws offer a significant benefit compared to nails and wood screws by preventing the material from splitting, cracking, or weakening at the point of fastening. The fundamental design of deck screws makes them the ideal choice for individuals seeking to build a strong and secure structure. Key components of deck screws include:
The head of a deck screw should resemble the flat countersunk surface of a wooden screw, but with a larger area to provide increased load-bearing capacity. It is designed in a bugle or flare shape to prevent the screw from sinking into the material it is fastened to. In contrast, wooden screws lacking this bugle shape may gradually embed themselves into the material over time, leading to issues like cracking and splitting.
Shank screws are built for lasting durability, with an aggressive point and sharp threading that swiftly and securely fasten into the material. The tapered and partially threaded design guarantees a tight fit in the wood, preventing any potential movement.
Threading on deck screws is sharp and deeply cut, allowing for quick and easy penetration into the material for secure fastening. In contrast, wood screws are typically less sharp and tapered, potentially affecting their long-lasting effectiveness.
Deck screws are more suitable for outdoor use because they are usually made out of corrosion-resistant materials like stainless steel or hardened steel. The sharper tips and deep threading on deck screws make them easier to drive into boards used in decking. Deck screws are suitable for use on hardwood and softwood, especially if used in a combination of a hardened stainless steel, such as 410 material and with an additional corrosion protecting top coat.
