This may be an odd request. I have a woodworking project whose design would be greatly improved by the use of something like this.

Basically, imagine a rocking horse...with a handle that is nothing more than two halves glued into a recess to form what appears to be a continuous dowel or handle.

Now, the strength of this can be improved by threading a wood screw into one dowel and screwing it to the other...to effectively screw the two together.

Does anyone make anything like this? Im not looking for other ways to do it, just whether or not anyone knows or has seen a double threaded...say #8 screw. I guess one end would have to be reverse threaded.

Edit: lol...looks like what I need is a DOWEL SCREW....imagine that. Wonder if Home Depot has them?

I have seen them.

edit:
Just saw your edit..I am sure Home Depot or Lowes would have them.

^^^I don't think so.

And yes, they sell double ended screws at places like Home Depot.

Correct...they don't have to be reverse threaded.

Another handy brain fart.

try this website. just used some of these to install tree lights. not exactly what you are wanting but a good starting point.

Fastenal or McMaster Carr might have it.


I've seen double screws at box hardware stores, too. Mostly they are like what is pasted above: One end pre-treaded for a permanent set, and the other self tapping wood screw.

lowes and home depot will both have this:



In fact here is a link to Lowes

how does one screw that in. I could do it with pliers but it might dick up the 2nd threads. Is that the "correct" tool to use?

Yes. Pliers wont mess up the threads bad enough to work on wood. But you can wrap the thread in a rag before you grab it with a pair of pliers.

My handle will be secured with wood glue, but this will make squaring it easier and make the joint far stronger.

Yes, my kids are hard on equipment.

The machine thread/wood screw has a square head drive in the machine end. Worked quite well for what I needed but doesn't seem practical for wood to wood

we used to use those screws on stairs. Connecting rails to bannister posts. just thought you might like to know that they are strong.
