Abstract
A screw anchor and method of forming such a screw anchor, the method comprising: forming a first male screw thread section on a metallic body and which is integral to the metallic body; and using a metal deposition technique to deposit a second male screw thread section on the metallic body; wherein the second male screw thread section is formed of metallic material having a greater hardness than the metallic body and is able to tap out a female thread in a hole in a support for receiving the first male screw thread section when the screw anchor is twisted into the hole.

A method of forming a screw anchor comprising:
- forming a first male screw thread section on a metallic body and which is integral to the metallic body;
- and using a metal deposition technique to deposit a second male screw thread section on the metallic body;
- wherein the second male screw thread section is formed of metallic material having a greater hardness than the metallic body and is able to tap out a female thread in a hole in a support for receiving the first male screw thread section when the screw anchor is twisted into the hole.
A screw anchor comprising a metallic body portion with a first male screw thread section integral to the body portion and a second male screw thread section that has been deposited on the body portion by a metal deposition technique, wherein the second male screw thread section is formed of metallic material having a greater hardness than the metallic body portion and is able to tap out a female thread in a hole in a support for receiving the first male screw thread section when the screw anchor is twisted into the hole.
A method of anchoring a screw anchor comprising:
- forming a first male screw thread section on a metallic body the first male screw thread being integral to the metallic body;
- using a metal deposition technique to deposit a second male screw thread section on the metallic body;
- wherein the second male screw thread section is formed of metallic material having a greater hardness than the metallic body and the second male screw thread is in helical alignment with the first male screw thread, tapping out a female thread in a hole in a support, receiving the first male screw thread in the female thread when the screw anchor is twisted into the hole.
