Abstract:
1. A sleeve interference fastener adapted to be installed in a hole of a structure comprising: a.) a sleeve having a head at one end and a tubular portion, the tubular portion having 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 structure; b.) a pin member having a pin head at one end, a locking portion at an opposite end, and a shank portion intermediate the pin head and the locking portion, c.) a locking member adapted to fit over the locking portion of the pin member; d.) wherein the sleeve is adapted to expand radially over the shank portion of the pin member to form an interference fit between the outer diameter of the sleeve and the hole of the structure so as to provide an installed position; e.) wherein, in the installed position, a first interface between the shank portion of the pin member and the inner diameter of the sleeve is substantially free from the low friction dielectric coating; and f.) wherein, in the installed position, the transition zone of the pin member and a second interface between the locking portion of the pin member and the locking member are substantially covered with the low friction dielectric coating.
