Abstract: A unique self-drilling anchor screw is configured so that it can be set and used to secure a first object to a second object using only one tool to save time and effort. A nut of the screw engages a nut stop when turning in reverse, thereby driving rotation of the screw in reverse. The screw has a drill bit tip adapted for drilling a hole while turning in reverse. A hole is drilled using the drill bit tip while turning the nut in reverse with a socket wrench of the one tool. After drilling the hole, the nut is turned in the forward direction with the socket wrench to engage a sleeve member of the screw, which sets the screw in the second object. Then, the nut is further turned forward using the socket wrench to tighten the nut against the first object located between the nut and the second object.

Abstract: A self-drilling anchor screw includes a shaft member. A drill bit portion is located at a first end of the shaft member. A threaded shaft portion is located along at least part of the shaft member. A transition shaft portion is located between the threaded shaft portion and the drill bit portion. A nut has nut threads adapted to thread onto the threaded shaft portion of the shaft member. The nut is located on the threaded shaft portion. A sleeve is located about the shaft member. At least part of the sleeve is located adjacent to the transition portion, and is capable of sliding along the shaft member for engaging the transition portion. A nut stop portion is located at a second end of the shaft member. The nut stop portion is adapted to prevent the nut from being unscrewed from the threaded shaft portion at the second end of the shaft member.

Abstract: A system and method of filing documents electronically or otherwise where the documents are secured from modification. The security provides proof that the items to be submitted have remained unchanged since the encryption was applied. A first installation account within a first installation is created, the first installation account having second installation account information relating to a second installation. A user account is stored in the first installation having information stored therein for a user of the second installation. A submission envelope is secured using a digital signature from the first installation, and this submission envelope is stored in the first installation.
