When it comes to outdoor woodworking projects, there are considerations for pieces that will spend their lives out in the elements. Having a quality finish is essential, but the fasteners also are subject to the damaging effects of the weather. Selection of woodscrews requires the evaluation of three qualities: strength, resistance to corrosion, and appearance Top bearing flush trim router bit Router Bit B0CKYCZMKH.
Generally woodscrews are comprised of iron based or some other metal. Iron based screws are quality material, but not practical for outdoor use due to their propensity to rust. The moisture that is naturally in the wood can cause rusting of the steel screws. Often steel woodscrews are coated with a rust-resistant product.
An alternative to the steel woodscrews is a plated woodscrew. Plating can be brass or zinc, with the later being the most popular choice. Although these plated woodscrews provide adequate protection from rust, the coating on them is rather thin. This is fine for indoor projects, but scratched finishes for outdoor projects can lead quickly to rusting.
There are now rust resistant steel screws available in home repair stores. These screws are corrosion resistant and do not cot much more than plated steel screws. The screws look very similar to a zinc-plated screw. It is designed from steel and has a coating of zinc-chromate. This is then covered with a clear coat of rust resistant material.
Another outdoor screw now available is made from steel then galvanized with multiple coatings of rustproof metals. These rust-resistant screws are both designed to withstand wet environments for longer periods of time.
Solid brass woodscrews were the standard for exterior applications for many years. The screws have a nice appearance and they do not rust. The problem is that the brass is soft and can easily strip or break. Pre-drilling is a requirement for this type of screw. This will help to eliminate some of the tension, but not a guarantee that the brass screws will not be damaged.
Stainless steel is another alternative for outdoor use. Though not as strong as a steel screw, there is certainly more durability than their brass counterparts. Boat builders prefer a screw that is silicon bronze. They are constructed from a copper alloy and have silicon added to the mix. These screws are corrosion resistant and will stand the test of time. These screws are also stronger than solid brass but not as tough as steel screws. They are very durable however and will compliment many outdoor wood projects.
The key is to find a rust-resistant screw that will accomplish the task of joining together your project pieces. When you want to create beautiful pieces for display and use, the last thing you want anyone to see is rust coming through on your work. Spending the few extra cents to get a protective screw will help keep your projects looking their best for many years to come.
