Description

• <p>★ <strong>Mechanical Advantage</strong> – Screws provide a mechanical advantage. Driving in a screw takes less force expended over a greater period of time than driving a nail into the same material. For builders using hand tools, this can make a construction project far easier when screws are involved. With power tools, screws require less force and place less strain on the tool’s motor.</p><p> </p>
• <p>★ <strong>Strength</strong> – Screws are very strong. Whereas nails may come loose once the materials they connect begin to expand and shrink over time, screws resist this problem and continue to create a strong bond. Because screws are stronger, a construction project can use fewer screws and place them farther apart, thereby reducing the cost of the project and speeding up the process.</p>
• ★ Resistance to Rust – The strong, tight bond of screws also makes them resistant to rust by preventing moisture and contaminants from coming into contact with the metal of the screw’s shaft. Even if the head of a screw begins to rust, the shaft will remain intact and continue to hold. This is another reason that screws are a better long-term solution than nails or staples.
• <p>★ <strong>Removal</strong> – Screws are easier to remove than other fastener types. While nails or staples may require a special tool to pry them loose, screws back out of their slots with the same tool that drove them in. Screws can also be re-used since they seldom bend during removal, and they can even be reinserted into the same holes without sacrificing strength.</p><p> </p>
• <p>★ <strong>Ease of use</strong> – If you have used screws in your woodworking project, you will know that they are very easy to apply, as they have sharp tips that can penetrate the wood much more easily. In most of the projects, you will be able to use wood screws without drilling any pilot holes. In addition, using wood screws can also help you finish the project fast in comparison to nails.</p>
