Steel Threaded Rods

1). The nail on the right is not only staining the lumber but it is rusting and will eventually effect the stability of the structure.

2). Any surface which is to be painted will soon show the rusting nail heads and a re-paint will become necessary much sooner.

3). The stainless nail on the left will last as long as the lumber and your expensive paint job will last as long as the paint.
4). Using stainless fasteners adds value to your project.   The difference in cost is minimal compared to the total cost of the structure.

5).  Stainless nails are stronger than plain steel fasteners too, so you have a win - win situation, for very little extra cost.

 

Which Stainless?

    Before you decide on your fasteners take a moment to decide which stainless grade you need?

You have a choice of stainless grade with many of our fasteners.
Type304or 316 Stainless Steel

all two grades of stainless steel are nickel/chromium and all are non-magnetic.

Type 304 stainless meets virtually all requirements except repeated exposure to sea water.

Type 316 is better in a coastal or harsh environment since it contains more nickel as well as 2% to 3% molybdenum, giving it superior corrosion resistance. For a harsh coastl enviroment it is better to use 316 SS.
All of the above grades are a major advance over other commercial choices.

There is absolutely no question that your best bet is stainless steel for any of the treated timbers and that includes wood foundations in particular, since the fasteners here are subjected to constant high humidity in addition to chemical attack.
Stainless-steel fasteners cost only a small amount more related to a total project budget, but they can have a significant effect on the life span of a structure.
