Why use Teflon fasteners?
Using Teflon coated fasteners has several advantages. First, they have a similar high level of resistance to rust/corrosion as stainless steel fasteners giving them a "longer life" than galvanized fasteners. A Teflon coating also gives fasteners lower friction levels reducing tork, making them much easier to fasten and looosen. They are also long term cost efficent. While Teflon fasteners are usually priced a bit higher than galvanized ones, they are stronger, reduce overall labor time and last longer while costing less then stainless steel options.
