long fasteners

[Dan Payne]

What are my chances of finding 5 inch #14 silicon bronze wood screws (prefer phillips head, countersunk but I'll take what I can get)? No luck with Jamestown or McMaster-Carr. If this is not availible on earth what should I use for an alternative? Stainless steel? Thanks! dp

No dice with Jamestown...or Mc Master-Carr

In a WBM article a few years ago, someone made up long screws to edge fasten a toe rail by cutting and welding a rod into the middle of a standard screw.

depends on what you are fastening.....in the past I have threaded bronze rod, soldered a nut on one end after spinning it on (silver solder), then drilling a hole oversized and wiping it with thinned epoxy...after it set, literally filling the hole with thickened epoxy and inserting threaded rod....held like grim death....

That's awfully thin for such a long screw.

[Bruce Hooke]

I wonder if it is time to think about why you need such a long screw and whether there is another solution to the problem. As Steve said, that is an awfully long, thin screw.

For example, if you are trying to screw down something that is 3" thick, could you simply countersink the screw heads more deeply?

new floor timbers. 1" plank (1/2" countersunk) 3" frame= 3 1/2". with a 4" screw I only have 1/2" of screw in that timber.

[Dan Lindberg]

I had a need for longer fasteners then I could get a while back....

I ended up using couplers (SS elec stand-offs) to join 2 pieces, a std bolt and a length of the bolt thread, to make a longer bolt. I loctited the threads and had to drill a slightly larger hole but it worked.

Shouldn't floor timbers be bolted, not screwed, to the keel?

I'm not a professional boat builder, but that seems like a pretty light fastening for that application.

[Dan Payne]

I am bolted to the keel, I'm re-screwing through the planks. 1" plank, 3' frames. I must be out of my mind. For a free boat this is getting pricey!

can be found here http://www.gtc-direct.com/products/displayProductSet.asp?SID=4,1,13,12,True,9,6,,0,0, False,0,0&page=1 These guys give excellent service, I'm a very satisfied customer....

[Paul Pless]

Another place to try would be Triangle Fastener, my self and my maintenance guys have used them for years, excellent customer service.

1" plank (1/2" countersunk)

Countersink is too deep.

If you are fastening plank to floor timbers, aren't you going into end grain of the floor timbers?

Or am I missing something?

Where are you hauled out?

[Tom Robb]

This just hold the plank to the frame? Why so long a screw, he asked supressing a smirk;)

[Bruce Hooke]

As I understand it, he is trying to tie together the plank, the frame, and the floor timber that rests on top of the frame. As to whether this means going into the end grain of the floor, it seems to me that this depends on whether there is reverse curve in the bilge and if so, how much.

Thanks all for the imput. Goulet in Texas was the solution. Not cheap, but I'm getting what I need.

The soldering on of the nut etc sounds a bit labour intensive .I tend to make long bolts out of hard copper and form a head with a die or if i need a hex head , thread the rod run it on and peen over the end ...its not coming off .Bronze would work the same way .

We usualy drift fasten floors. I use bronze rod and clinch rings we have cast from our own patterns.

What alloy for the clench rings Jay ?

What alloy for the clench rings Jay ?
Phosphor Bronze as it will take the shock of final clinch pounding.

Thanks Jay,I use a leaded bronze we call gunmetal.
