Our Silicon Bronze ring nails (also referred to as bronze boat nails or ring shank nails) are threaded with annular ring barbs to create a locking effect and resist pullout stresses. This thread form provides holding power comparable to wood screws with maximum back-out resistance.
We recommended silicon bronze nails for wood or plywood joints where maximum resistance to withdrawal loads is required.
Note: Not recommended where shear, lateral or racking loads are significant, or for end-grain nailing.

Questions & Answers about Silicon Bronze Threaded Annular Ring Nails:
2013-03-28JIM WOLFORD asked: What is a 12 gauge nail in inches?
+Expand Answers
2013-03-28LYLE BOGART: Mine measure at 0.105 inches.
2013-03-28BRAD KURLANCHEEK: A nail's gauge is a nail's width/diameter, and not its length. A 12 gauge nail has a thickness or width of diameter of the shank of the nail, of about 1/10th of an inch.
2013-03-28DAVIS GRIFFITH: 12 ga. bronze ring nail: threaded section is .120" dia., unthreaded section under the head is .110" dia, head is .245" dia.
2013-03-29GIULIANO GIROMETTA: !2 gauge nail should be 0.1055 mil (Close to 7/64")
2013-01-07DARRYL MCGOWAN asked: are the nails made in the States or China ?
+Expand Answers
2013-01-07TERRY JENKINS: To be honest I don't recall. Unfortunately, the cats decided the boxes looked like fun toys (even with the nails inside) so they are long gone.
Sorry I can't be of better help.
2012-11-01BRIAN MEINUNG asked: how do you restore the silicone bronze head back to its lustre? after it has turned dark brown
+Expand Answers
2012-11-01JOHN MARTIN: Most of the time, I cover these up with epoxy, so I don't have this problem. However, depending on what type of surface surrounds the nail head (paint, varnish, tung oil, etc), I would suggest using "Never Dull" silver/brass polish, but test it on your surrounding surface first. If you need a non-chemical solution, you may try some fine steel wool or a ~400 grit sandpaper. (Maybe even use a dremel polishing attachment.) I am assuming that this is simply surface oxidation. If the silicon bronze has reacted below the surface and the darkening is throughout the metal, I doubt either solution will work.
2012-11-01LYLE BOGART: Brian,
I've never even thought about it. I prefer the patina which time and elements bestow upon bronze hardware.
Cheers,
lyle
2012-11-01DAVID CALLOWAY: I've never tried, but I would bet that "Bartender's Friend" cleanser would work. Flitz metal polish too.
2012-09-20ROSALIND HILDRED asked: How long is the smooth shank on the 3/4" nail? If they poke through and I need to bend the tips over, will they break off? Or better to nip them off? I'm considering using them to fasten copper sheet to 5/8" planking.
+Expand Answers
2012-09-20JOSEPH ANTIN: probably 1/4 inch.
i have never had them extrude but i do not think they will break off. you could certainly nip off the end, suppose.
2012-09-20MR. MIKE SNOOK: You really need to use 1/2 inch nails. They are hard to find but are available.Search around the web.
2012-09-20JOHN MARTIN: The smooth portion is roughly 1/8"-1/4", if memory serves. The silicon bronze is very soft, I would recommend nipping them with some side cutters and then smoothing out with some sandpaper or a file. If you have a dremel, you could grind them, but the low melt point sometimes "smears" the nail a little instead of giving you a clean cut.
2012-10-26DWIGHT HALES: The smooth shank is not long, but should be enough for metal cladding. (I'd give an exact measurement, except I don't have a nail in front of me.)
I would suggest nipping the nails off instead of bending them over, unless you have an extra hand for holding dead weight against the nail head as you make the bend.
2012-09-05A shopper asked: Will these nails stain a natural wooden deck over time similar to copper nails?
+Expand Answers
2012-09-05STEPHEN WALSH: It depends on their exposure to the elements. They will stain if exposed over time to air and salt. Maintenance is the key to controlling it.
2012-09-05PAUL MILLER: I've not used them on decking, only boats and canoes but they are exposed to water and don't stain the wood.
Copper oxidizes rapidly Silicon Bronze does not.
2012-09-05DAVID CALLOWAY: My experience has been that they do not, though they do turn dark brown eventually. I would guess that it also depends on the species of wood. Soft woods absorb more water than hard woods, so more water migration in each wet dry cycle. The only way I know of to be sure, is to countersink the heads and then cover with a bung or wood putty.
2012-03-17EDWARD PACIOREK asked: Which gauge of bronze nail has a 5/16" head? I'm trying to match some other work. Ed P :-)
+Expand Answers
2012-03-21DON ELLIOTT: I have 3/4, 1 and 1-1/4" 14 gauge. They all have heads slightly less than 1/4 diameter. Not sure what next gauge head size would be.
2012-03-06A shopper asked: are these ring nails good for old wood.?
+Expand Answers
2012-03-06VICTOR GOOCH: In my experience these nails are best used for any wood, old or new. Unlike other nails, they do not loosen over time. If I had an extremely hard wood, I might be tempted to drill a small pilot hole.
2012-03-06DAVID THOMAS: By their nature, the bronze nails are on the softer side. Meaning, if the wood is very dense (i.e. old wood), they will bend easier. Something you will have to experiment with. If the 'old' wood is soft from rot, then, you have other issues to deal with.
For my projects, the nails have worked great. Once in, they stay in, which is what you want out of a ring nail.
What species of old wood are you dealing with?
2012-03-06JAN BLOOM: This really depends on the condition of the wood. If it is good solid wood you should have no problem using the bronze ring nail. If it is "soft", degraded to almost rotten then replace the wood or try using a penetrating epoxy (CEPES) to reinforce the wood before using the ring nail. A very good rule of thumb is to predrill undersize when using bronze ring shanked nails. This is especially helpful in old hardwood like white oak where the resins have set up and hardened over the years. Or if you have any concerns about splitting old Teak or Mahogany when trying to drive in the nail.
2012-03-06MR. MIKE SNOOK: Yes they are fine. If in doubt in very hard wood predrill with a small pilot drill.Regards Mike.
2012-03-06CARL KENNEY: i would go with stainless steel in the future, the bronze head is to soft
2012-03-06ANDREW JAHN: Don't know for sure, but if the wood is any good, the nails should hold. For a general discussion of holding power of nails, see Richard Jaegels' article in Wooden Boat #225.
2012-03-07JOE LUDGATE: THEY WORKED GREAT ON MY 1955 PENN YAN. I U SED THEM TO REFASTEN THE BOTTOM PLANKS.
2012-03-14MARY TRAYNELIS: Yes, if there is still integrity in the wood. In new wood, these go in & do not come out. We used a smaller bit to pre-drill, when needed.

I don't think I am going to be a lot of help to you.
I have installed all the s/b nails and do not have one left to throw my calipers on....but.....the shank below the head is 3/16th".

2012-02-09PETE KAUNECKAS asked: What size pilot hole do I need to use these nails? Both for soft (juniper) and hard (oak) woods.
Thanks
+Expand Answers
2012-02-09AL BUKOWSKY: Pete,
I always drill the pilot hole smaller than the size of the nail. I cannot tell you what size as the boat nails come in diferent sizes.
Al
2012-02-09KATHERINE MCCOLLAUM: I used up these nails several years ago so I cannot measure them to tell you exactly. But I use as a general rule of thumb for ring shank nails, pilot hole bit is 1/2 the diameter of the nail for soft wood and 3/5 diameter for hard wood. If you are nailing a soft wood to a hard wood use the 1/2 diameter for your pilot hole. Hard wood to a soft wood use the 3/5 diameter and a longer nail. Hope that helps.
2012-02-09JOSEPH HOLLOWAY: For the Juniper I would not use a pilot hole for the oak I would make the hole slightly small than the shank diameter.
2012-02-10LISLE POSEY: Drill a pilot hole 1/64" smaller than the SHANK of the nail in hard woods.
No pilot hole should be needed in soft woods.
Lisle
2012-02-14Pete Kauneckas: Thanks Lisle for your recommendation.
Pete Kauneckas
2012-02-10DAVID PRICE: Never worked with juniper.Oak splits were easely I recomend a pilot hole 3/4 the diameter of the nail
2012-02-10DAVID CALLOWAY: Hi Pete, I use a pilot hole that is a small as I can without spliting or damaging the wood. Softer wood (pine) smaller hole, harder wood (maple) larger. I keep the hole smaller than the shank so that there'll be good grab. Try a few holes in scrap with the grain, near an edge and see what works. These nails are more brittle than steel (even stainless) and don't bend back well. Dave
2012-02-10DUANE `FISH: Sorry I do not ha e an answer for you. I would do a couple test holes in each wood an see how easy-hard they are to remove.
2012-02-10MICHAEL HERRON: Pete, The process I use is cutting the head from the top of the nail and using it as a bit to drill th pilot hole. They get dull after10-20 holes so I would cut another bit from the nails. It's not elegant, but it works well
2012-02-14Pete Kauneckas: Thanks Michael for the information. Will try out your recommendation.
Pete Kauneckas
2012-02-10WILLIAM HOLLINGS: Per "Boatbuilding Manual", Robert Steward, 4th ED., page 90.
"Pilot hole size recommended is 50 to 70% of the nail diameter... and about 80% of the nail length."
For soft woods tend towards the 50%, hardwoods towards 70%. Do some test trials before drilling them all.
2012-02-14Pete Kauneckas: Thanks William for the reference book and the information.
Pete Kauneckas
2012-02-10MICHAEL BOYD: If the hole is too small the nail will tend to break when driving, too large and it can be removed with a claw hammer. The holding power of the wood can make a big difference. So, I always do a test on a piece of scrap to find the right pilot hole size.
2012-01-06A shopper asked: Should I expect a negative reaction when using bronze tacks to secure copper flashing (i.e., dissimiliar metals)? BW - Savannah. GA
+Expand Answers
2012-01-06PAUL BROWN: I do not have first hand experience with using the silicon bronze nails in copper. However, I believe these two are relatively close together in terms of the Galvanic series so I would expect them to be fairly compatible. The Delaware Sea Grant web site has a publication on Galvanic corrosion that explains this.
2012-01-06MR. MIKE SNOOK: No. Copper & silicone bronze are very close matched on the galvanic scale. Unless you are putting them underwater in salt water for long periods of time with out cathodic protection in which case you might consider the use of copper nails & tacks. Regards Mike.
2012-01-06TODD FILLINGHAM: You want the flashing to be less noble than the fastener as the large area of the flashing would show appreciably less galvanic corrosion as it would be distributed over the large area. Silicone bronze is very close to copper on the galvanic series in sea water and it happens to be on the cathodic side (more noble) of copper, again in sea water.
I would think you could use them.
http://corrosion.ksc.nasa.gov/galcorr.htm
2012-01-06ROBERT BARNES: Most likely not because bronze and copper are not generally reactive type metals with each other. I use these nails to fasten planks to the bottom of my boat and when the coast guard had me pull them for an inspection the ones that have been in the boat since 1978 almost look like new sittting in salt water for all those years.
2012-01-06URBAN BOATBUILDING BRIAN THORKILDSON: Silicon bronze and copper are very close to each other on the galvanic scale, and so the electrical potential between them is negligible. My instinct suggests that you will be fine using these two metals together in most applications, unless your boat is in a very busy saltwater harbor with lots of loose electrical current.
2012-01-06DAVID CALLOWAY: Silicone Bronze is made with a combination of metals (roughly: 88% copper, 10% tin, 2% silicon; I don't know the values for these exact nails), and varies by manufacturerer. I've used these nails in combination with stainless fasteners around salt water and had no problems.
2012-01-07NORMAN GOLM: Galvanic corrosion happens went very different materials are adjointed. Copper and bronze are very similar I would except no problems. Basically batteries are made with very different materials on the periodic chart and one metal corrodes.
2012-01-07KEVIN ZEMBOWER: I wouldn't think so, but I'm just guessing. I've never used silicon bronze nails with copper, and I'm not a chemist or metallurgist. However, silicon bronze is 97% copper.
2012-01-09JAMES MANGES: I have used these on boats around Lake Erie and haven't had any issues. I have never tried it with copper flashing. I have never seen any reactions between bronze and copper in boats or otherwise. Thanks, Terry
2012-01-09DAVID KAPPEL: My amateur understanding is that bronze has copper as part of its alloy and thus I would expect them to be compatible. However, I have used them only with copper flashing and with wood.

Comments about Jamestown Distributors Silicon Bronze - Threaded Annular Ring Nails:
I used these nails to create a look similiar to copper nails and roves on my gunwales. Pre-drill nail holes,especially in hardwoods, a bit smaller than shank to avoid splitting your wood trim. I drilled from both sides and drove the nails towards each other in order to center them on the inner and outer 'wales. Only split 2 of 30 spacers holding inner 'wale away from top strake of boat..easily fixed with epoxy and clamp. I also dipped them in epoxy before I drove them home to seal the holes from any water intrusion. They really look great after a little burnishing with superfine sandpaper and a coat of epoxy followed by varnish.
