"TONY KAPECHUK: Hi, my name is Tony. And on behalf of Expert Village, I'll be showing you how to turn this check socket into a laminated definitive prosthesis. Now, we've got our finished laminated socket and we're ready for assembly. Some of the tools we'll be using is a 4-millimeter wrench, a torque wrench, Loctite. We've got our male pyramid, our shuttle lock, foot pylon and our liner. We'll go ahead and we'll drop the lock into place, making sure our hole lines up with the hole that's in our socket, like so. Then we'll apply some thread locking liquid through our threads of our screws. Now, we can set that on our pyramid plate and insert the screws. These are four-millimeter metric screws. We'll use a star pattern to tighten the screws, and then we'll torque it with the manufacturer's specs."
