Well I found the instructions

Use only the provided screws,nuts and O-rings.
I went to Newegg, looked up your HS, clicked on manufacters site and watched the flash presentation. There is also a 19 page pdf that covers all board types.
The screws have shoulders on them and the nuts that are installed with a phillips screw driver. They appear to be set-up so they can't be over tightened. They got to make this stuff dumby proff for us
