8. The security tag of claim 7 , wherein the substantially non-slip material provides a textured surface.

9. A security tag configured to releasably attach to an article, the security tag comprising:

a tack, the tack including a tack head and a pin shank extending from the tack head, the pin shank having a maximum diameter less than 0.9 millimeters;

a housing, the housing including:

an electronic article surveillance (EAS) element;

a clutch, the clutch configured to releasably retain the pin shank after insertion into the housing, the clutch retaining the pin shank if up to an eighty pound pull force is applied to the tack; and

the tack head including a tack mating surface and the housing including a housing mating surface substantially facing the tack mating surface when the pin shank is releasably retained by the clutch, at least one of the tack mating surface and housing mating surface being a textured surface, the textured surface providing resistance to movement of a portion of the article that is located between the tack and the housing when the tack is releasably retained by the clutch mechanism.

10. A security tag configured to releasably attach to an article, the security tag comprising:

a tack, the tack including:

a tack head, the tack head including a tack mating surface, at least a portion of the tack mating surface having at least one of a textured surface and a substantially non-slip surface; and

a pin shank, the pin shank extending substantially orthogonally from the tack mating surface;

a housing, the housing including:

an electronic article surveillance (EAS) element;

a clutch, the clutch configured to releasably retain the pin shank; and

a housing mating surface, the housing mating surface substantially facing the tack mating surface if the pin shank is releasably retained by the clutch.

11. The security tag of claim 10 , wherein the substantially non-slip surface includes a substantially non-slip material, the substantially non-slip surface at least partially overlapping the portion of the housing mating surface if the pin shank is releasably retained by the clutch.

12. The security tag of claim 10 , wherein the pin shank has a maximum diameter of less than 0.9 mm; and

the clutch configured to retain the pin shank if up to an eighty pound pull force is applied to the tack.

13. The security tag of claim 10 , wherein the pin shank is a groove-less pin shank.

14. The security tag of claim 10 , wherein the non-slip surface includes a textured non-slip material.

15. The security tag of claim 10 , wherein the pin shank has a maximum diameter of 0.76 millimeters.

16. A method of attaching a security tag to an article, the security tag including a tack and a housing, the tack having a tack head and a pin shank extending from the tack head, the pin shank having a maximum diameter of less than 0.9 millimeters, the housing including a ball clutch configured to releasably retain the pin shank if the pin shank is inserted into the housing, the housing further includes an electronic article surveillance (EAS) element configured to emit a detectable response if introduced to an interrogation signal, the method comprising the steps of:

a) inserting the pin shank through the article; and

b) inserting the pin shank into the housing, the ball clutch configured to releasably retain the inserted pin shank if up to an eighty pound pull force is applied to the tack.

17. The method of claim 16 , wherein the ball clutch includes a plurality of retaining balls disposed on substantially the same plane, the plurality of retaining balls configured to releasably retain the inserted pin shank.

18. A method of attaching a security tag to an article, the security tag including a tack and a housing, the tack having a tack head and a pin shank extending from the tack head, the pin shank having a maximum diameter of less than 0.9 millimeters, the housing including a ball clutch configured to releasably retain the pin shank if the pin shank is inserted into the housing, the housing further includes an electronic article surveillance (EAS) element configured to emit a detectable response if introduced to an interrogation signal, the method comprising the steps of:
