the type of fastener in the photo Tom?
You drill a hole and thread in the fastener that has large wood threaded body and then use the machine screw threads on the inside to secure it. I have seen them, but never actually used them myself.
They come in a lot of sizes and threads, but this was the only photo I found in a quick search.
