Traditional Rose head copper cut nails are used with matching copper roves to form a copper rivet. These nails are extremely robust, easy to drive and when the wood fibers become damp and swell, will never work loose.
Copper Roves are slightly conical washers. A copper nail is hammered through the joint, a rove is pushed over the end (concave side inward) and the nail is peened over forming a copper rivet. Also similar to clinch or clench nailing. Copper rivets are often utilized in classic planked wooden boat construction.

Traditional copper cut nails used with matching copper roves. These nails are extremely robust, easy to drive and when the wood fibers become damp and swell, will never work loose.
Riveting is a matter of through nailing two pieces of wood, slipping a washer over the pointed end of the nail, pushing it down the shank against the wood and then nipping off the excess nail leaving just enough excess to peen over the washer to lock it tight.
All copper riveted connections are made using two parts: nails; called the "rivet" and washers; called "burrs" or "roves". The rivets are generally just copper common nails; however, European boat-builders generally prefer the conical head and square shank of the Rosehead Boat Nail. Either way, the nail goes into the slightly undersized pre-drilled holes and through the pieces of wood to be joined. A burr with a slightly undersized center hole; to provide an interference fit, is then placed over the nail point to be driven down the nail shank. At this point you will need a Rove Set tool. We offer one here but you can make your own with a piece of rounded hardwood or a 1" hardwood dowel about 6" long. Drill a hole in one end, on center into the end grain deep enough to accommodate the exposed length of nail and size it slightly larger in diameter than the nail shank, and now you have a Rove set.
A heavy back-up tool is required to "buck-up" the head of the nail prior to setting the burr and forming the completed connection. We offer a heavy (4) pound hammer with a short handle suitable for this application.
Now, to make the copper rivets connection, first tap the nail through the pre-drilled pieces of wood to be joined and back-up the head with the "buck" hammer. Next, place the burr over the nail and drive it down the exposed nail shank using the rove set tool applying light taps from a hammer. The burr should seat firmly against the wood. Using a set of diagonal cutters nip off the excess nail leaving about a nail diameter in length beyond the burr to peen over. Holding the "buck" hammer hard against the nail head, take a lightweight ball-peen hammer (STN-54016) and start tapping with the flat end to mushroom over the cut nail stub. Finally using the rounded end of the ball-peen hammer tap the mushroomed stub around the edges forming the end to lock down the burr and draw up the connection.

2012-11-09DANIEL SHOENHAIR: I used liver of sulfur and they patina'd just fine. Had to leave them in the solution a little longer than normal, so maybe there is a coating, but the liver of sulfur turned them black, just like I wanted. Hope this helps.
2012-11-09WILLIAM WERNER: Sorry, I bought these a few years ago...they were exactly what I wanted but I do not remember if they were coated.

2012-11-09RONALD JOCHIM: Used these nails and they are not coated. Be sure to get the nails for your use but do not buy nails that are overly long as they will be difficult to drive without bending...
2012-11-09DONALD POTTER: Hi Greg,
I used these in conjunction with some copper post caps for our grape vine trellises. To my knowledge, all of it weathered and changed color nicely, including the nails.
So this was in an outdoor situation being "watered" year around including our irrigation. My recollection is that the post caps and nails turned about the same time and rather quickly.
So I cannot conclusively answer your question; however, my guess is that they are not coated.
Thats all I got, good luck.
Donald
2012-11-10Greg Coutta: Thanks for the replies everybody, I will give them a try. Everyone was a big help!
2012-11-13PUDDLE DUCK TOYS JEROME CIESIELSKI: Greg
I do not believe these nails are coated. I used them in several boat projects, some of which set around for a year or so. They did develop a slight patina around six months. But if there was any coating , it was possible it was removed during installation. If there was any oil or coating applied by the maker to keep them looking "store fresh", you could remove it by soaking them in Acetone for a few hours and then rinsing with hot water before installing. As a side note, I used nails from several distributors and found that Jamestown products are more consistent in size than others. Hope this is a help to you.

There is a website you can go to that has the conversion table you're looking for, but Jamestown Distributors will not allow me to put web addresses in this answer. I will break it up in pieces for you. Go (3)w stainless-fasteners dot com forward slash conversion1. and include the h t m suffix.
Hope this helps.
