A sleeve interference fastener adapted to be installed in a hole of a composite structure comprising: a) a conformable sleeve having a head at one end and a tubular portion, wherein the tubular portion has an inner diameter and an outer diameter, wherein the outer diameter of the tubular portion is less than an inner diameter of the hole of the composite structure, and wherein the conformable sleeve is comprised of at least one first material having a hardness of X; and b) a pin member, wherein the pin member has at least a pin head at one end, a locking portion at an opposite end of the pin head, and a shank portion therein between, wherein the shank portion, located below the pin head, has a diameter greater than the inner diameter of the tubular portion of the conformable sleeve, and characterized in that the pin member is comprised of at least one second material having a hardness of Y, wherein X is sufficiently less than Y so that, in an installed position, at least a portion of the at least one first material of the conformable sleeve conforms to a contour of an inner surface of the hole so as to create a continuous electrical contact at an interface between the inner surface of the hole of the structure and the conformable sleeve, wherein, upon a pressure from the shank portion of the pin member, the conformable sleeve is adapted to expand radially over the inner surface of the hole to form an interference fit between the outer diameter of the sleeve and the hole of the composite structure so as to provide the installed position, and wherein, to facilitate a movement of the pin member through the conformable sleeve, the fastener further comprises a lubricant, wherein the lubricant comprises a conductive solid film material. a) a conformable sleeve having a head at one end and a tubular portion, wherein the tubular portion has an inner diameter and an outer diameter, wherein the outer diameter of the tubular portion is less than an inner diameter of the hole of the composite structure, and wherein the conformable sleeve is comprised of at least one first material having a hardness of X; and b) a pin member, wherein the pin member has at least a pin head at one end, a locking portion at an opposite end of the pin head, and a shank portion therein between, wherein the shank portion, located below the pin head, has a diameter greater than the inner diameter of the tubular portion of the conformable sleeve, and characterized in that the pin member is comprised of at least one second material having a hardness of Y, wherein X is sufficiently less than Y so that, in an installed position, at least a portion of the at least one first material of the conformable sleeve conforms to a contour of an inner surface of the hole so as to create a continuous electrical contact at an interface between the inner surface of the hole of the structure and the conformable sleeve, wherein, upon a pressure from the shank portion of the pin member, the conformable sleeve is adapted to expand radially over the inner surface of the hole to form an interference fit between the outer diameter of the sleeve and the hole of the composite structure so as to provide the installed position, and wherein, to facilitate a movement of the pin member through the conformable sleeve, the fastener further comprises a lubricant, wherein the lubricant comprises a conductive solid film material.
