Most screws use Philip’s head because it is more common and considered easier to drive.īut the star and square drives may work quite well. The type of screw head makes a difference. The length and gauge of the screws and nuts should match the thickness and hardness of the wood. This is a basic determination based on the thickness of the wood and the type of work being performed. There are several factors to consider when purchasing the type of screws and nuts that will work best for your project.įrom practical to appearance, some factors to consider include the following. What to Look for Before Buying Woodworking Screws and Nuts? Remember that they tend to be more expensive and cannot be used with galvanized structural connectors because of the potential chemical reaction. Grade 316 is generally the best for copper-treated wood when used in coastal areas. Such properties make galvanised screws and nails perfect for outdoor use. This process means the nails have a protective barrier which makes them resistant to rust and corrosion. Stainless Fasteners: It’s best to choose grades 304 or 305, which provide good corrosion resistance. Galvanised screws and nails have a zinc coating meaning that they have undergone a galvanisation process. It also prevents copper and water from touching the steel or zinc inside the screws. This is to protect copper-treated wood from becoming corroded. They are also strong, resist corrosion, and can be used for many different applications. One noticeable advantage of zinc-plated nuts and bolts is the fact that they are far more affordable compared to stainless steel versions. However, they are not fully resistant to water, which is why they are not recommended for high humidity or underwater environments. Zinc-plated nuts and bolts offer a number of uses, including projects that are outdoors, since they can resist the elements while providing additional resistance to corrosion. These are basically steel nuts that are electroplated with zinc and are among the most popular choices.

This is why installing stainless steel nuts is normally left to a professional who has the tools to prevent galling from occurring. The only downside is that when stainless steel nuts are installed, they may cause galling or seizing to occur. Plus, the integrity of the nut will not be affected when scratched or dinged. Stainless steel is known for its durability and resistance to corrosion. What to Look for Before Buying Woodworking Screws and Nuts?.Can You Use Zinc Coated Screws in Pressure Treated Wood?.
