Anchor stud and method of forming an anchor stud
An anchor stud includes a stud portion including a body portion having a first end that extends to a second end though an intermediate portion. A wedge member is operatively coupled to the second end of the stud portion. The wedge member includes a body having a generally frustoconical profile and is formed from a material having a Vickers hardness of between about 218 HV and about 290 HV. A sleeve element is positioned on the stud portion at the second end adjacent the wedge member. The sleeve element is formed from a material having a Vickers hardness of between about 218 HV and about 290 HV.

4. The anchor stud according to claim 1 , wherein the sleeve element is formed from a material having a Vickers hardness substantially identical to the Vickers hardness of the material forming the wedge member.
5. The anchor stud according to claim 1 , wherein the Vickers hardness is measured to a depth of between about 0.005 inches (0.127 mm) and about 0.025 inches (0.635 mm).
6. The anchor stud according to claim 1 , wherein the wedge member is formed from a hypoeutectic steel.
7. The anchor stud according to claim 6 , wherein the wedge member is formed from a medium carbon steel.
8. The anchor stud according to claim 6 , wherein the medium carbon steel is between about a 1030 steel and about a 1060 steel.
9. The anchor stud according to claim 1 , wherein the sleeve element is formed from a hypoeutectic steel.
10. The anchor stud according to claim 8 , wherein the sleeve element is formed from a medium carbon steel.
11. The anchor stud according to claim 10 , wherein the medium carbon steel is between about a 1030 steel and a 1060 steel.
12. The anchor stud according to claim 1 , wherein the sleeve element is formed from martensite steel.
13. The anchor stud according to claim 12 , wherein the sleeve element is formed from pre-hardened martensite steel.
14. An anchor stud comprising:
a stud portion including a body portion having a first end that extends to a second end though an intermediate portion;
a wedge member operatively coupled to the second end of the stud portion, the wedge member including a body being formed from a first hypoeutectic steel having a Vickers hardness of between about 218 HV and about 290 HV; and
a sleeve element positioned on the stud portion at the second end adjacent the wedge member, the sleeve element being formed from a second hypoeutectic steel that is substantially identical to the first hypoeutectic steel, the second hypoeutectic steel having a Vickers hardness of between about 218 HV and about 290 HV.
15. The anchor stud according to claim 14 , wherein the sleeve element has a Vickers hardness substantially identical to the Vickers hardness of the wedge member.
16. The anchor stud according to claim 15 , wherein the Vickers hardness of the wedge member is measured to a depth of between about 0.005 inches (0.127 mm) and about 0.025 inches (0.635 mm).
17. The anchor stud according to claim 16 , wherein the Vickers hardness of the sleeve element is measured to a depth of between about 0.005 inches (0.127 mm) and about 0.025 inches (0.635 mm).
18. The anchor stud according to claim 14 , wherein the sleeve element is formed from martensite steel.
19. The anchor stud according to claim 18 , wherein the sleeve element is formed from pre-hardened martensite steel.
20. The anchor stud according to claim 14 , wherein the first hypoeutectic steel forming the wedge member includes a medium carbon steel between about a 1030 steel and a 1060 steel.
21. The anchor stud according to claim 14 , wherein the second hypoeutectic steel forming the sleeve element includes a medium carbon steel between about a 1030 steel and a 1060 steel.
22. A method of forming an anchor stud, the method comprising:
forming a stud portion including a body portion having a first end that extends to a second end though an intermediate portion;
providing a wedge member formed from a first hypoeutectic steel having a Vickers hardness of between about 218 HV and about 290 HV at the second end of the stud portion; and
attaching a sleeve element to the stud portion at the second end portion adjacent the wedge member, the sleeve element formed from a second hypoeutectic steel that is substantially identical to the first hypoeutectic steel, the second hypoeutectic steel having a Vickers hardness of between about 218 HV and about 290 HV.
23. The method of claim 22 , wherein at least one of the first hypoeutectic steel forming the wedge member and the second hypoeutectic steel forming the sleeve element includes a medium carbon steel between about a 1030 steel and a 1060 steel.
24. The method of claim 22 , wherein the sleeve element has a Vickers hardness substantially identical to the Vickers hardness of the wedge member.
