    Yeah, I've contacted schaeffler, NSK, THK, etc, and they don't seem to do this concept as off-the-shelf. I've seen this concept elsewhere, such as in the image below: (http://neurowiki2014.wikidot.com/individual:repetitive-transcranial-magnetic-stimulation-rtms) I like the concept of a...

    Compression in material due to a tapered variable pitch headless screw

    Thanks dhengr & tbuelna. We have already characterized the relative displacement of the two bone pieces, but trying to characterize the compression created between two bone fragments is where we'd like to go. Most papers on the subject simplify the bone structure to two "bone bricks" being...

Now the main features of these types of screws are: - Variable pitch; screw tip has a coarse thread while the head has a...
