I don't believe she is talking about using it for structural items, like bulkheads... Denise is smarter than that. I believe she may be intending to make a table or other furnishings for her boat with pocket screws. There should be no problem with doing that IMHO.

It looks to have a raised thread like a drywall screw.

It seems to be less about the design of the screw, and more about the jig that makes it easy to drill the counter sink hole.

I would think the question about using this to attach bulk heads would be more about using this method than this particular screw.

As for me those screws have no place on a boat...the idea of "toe-nailing" has its place...if used for attaching bulk heads I'd us a lot of screws, SS or bronze.
However, I would prefer other more robust methods that will be easier to plug the holes.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

That sounds OK...but for the money and work I'd use dowels or those football looking wafers.

In certain applications pocket screws are superior to biscuits. I agree it is more about the pocket itself and the application of use rather than the actual screw. If the SS pocket screws were way expensive I would just use a similar sized SS pan head screw.

Biscuits....thatís the word I was looking for!

I agree soulsailor, screws may have some advantage, no clamps for one and having a real mechanical fixing that does not rely 100% on the glue could be worth while advantages.

There are lots of woodworking joints because there are lots of applications. I like the Kreg setup for cabinet work. Once you're used to their jigs you can go pretty fast.

Biscuit joints, especially if you use two offset biscuits are surprisingly strong. But it all depends on what you're trying to do, what kind of wood you're using and what kind of environment it will live in.

Fine Woodworking did a stress test of woodworking joints a while back. You can find it on their web sites as a PDF. The results are pretty interesting if you enjoy wood butchering. taunton.com/finewoodworking/ToolGuide/ToolGuidePDF.aspx?id=31926

I say use whatever tool / joint will get the job done.

As with any question the answer is 'It Depends'. It depends on what your use is. I do alot of woodworking, cabinets and furniture, so if you are making something like that then yes pocket screws work very well. I would also use a polyurethane glue like Gorilla glue also unless you plan on taking it apart. Another option if you are joining corners is to use dowels and glue, or countersink screws. I would only use screws if you are using SOLID wood. If you use screws in plywood it will delaminate, maybe not at first but over time it will split between the plys.

before you get to into whatever you're building, look into Hi low screws if you are going to be working with plys and softwoods

I have used the Kreg jig on several small projects and have been very pleased. Used in conjunction with epoxy sealed/glued wood and then filling the hole with a thickened epoxy I have what appears to be a bullet proof joint. 2 years latter there are no signs of problems. David
