Long long time ago. Before the internet. Before computers. I saw a guy attaching aluminum trim to the exterior of a house. People normally cover the trim with this material when doing vinyl siding. Trim coil comes in different colors and is usually bent with a portable aluminum brake. This guy was using a staple gun. I asked him about the staple gun. He explained that it was the same staple gun that carpet layers use. He had staples that were made from monel and painted white to match the aluminum trim.
[Monel = A nickel-copper alloy with high tensile strength and resistance to corrosion]
I then bought the same type of staple gun and a box of monel staples painted white. Years later the staple gun broke so I bought a new one. Many boxes of staples later the Duo-Fast company stopped making the monel staples colored white, so I bought stainless steel staples not painted. Life has been great. Use these staples to fasten aluminum trim around windows and doors. Mostly in places where the staples can be hidden. Also use these staples to fasten vinyl soffit panels to the bottom of overhangs.
Now the Duo-Fast company has stopped making these staples in stainless steel. I have been searching and searching. All I can find is galvanized steel. Think that steel is a poor choice for fastening aluminum and vinyl to wood. Steel will react with aluminum in a bad way. With vinyl siding, steel rusts and leaves brown stains dripping down.
Am I the only one on this planet who wants to buy these staples? How do people fasten carpets to wood boats and other wet places? I have talked to other contractors and they mostly are using hammer and nails for soffits and aluminum trim. There are wider crown 3/8 inch stainless upholstery staples but I want my favorite narrow crown staples so the heads are less visible.
Here are details on these staples:
5400 series is 3/16 inch crown
Gauge is 20
Second two numbers is length in 1/32s
C = Chisel Point
D = Divergent Point
M = Monel
SS = Stainless Steel
Here are part numbers on the DUO-FAST boxes I got.
3/8" No. 5412-CM
and
1/2" No. 5416-D STAINLESS
Here is a picture of my staples. Need more soon!

Where to buy these?
Here is picture of a electric staple gun similar to mine. Prediction for the future - Tool makers will make cordless carpet layer staple guns.

Here is picture I found on the internet. Man installing vinyl soffit panels.

Finally found a staple company that will make staples special for me 5416-DSS Only problem is I have to buy a boat load! Group buy anyone? I have done stupid things before, but now it's looking like I will be going into the staple business.
