摘要： A method of installing a fastener into a structure, comprising the steps of providing a fastener having a pin member including an elongated shank having a first end, a second end opposite the first end, a cylindrical shank portion having an outer surface, a head located at the first end of the elongated shank, the head including a bearing surface located on the underside of the head, and a threaded portion located at the second end of the elongated shank and a seal element adapted to be positioned on the pin member such that the seal member is juxtaposed with the bearing surface of the head of the pin member; and installing the fastener into the structure in an installed position.

摘要： A pin member for a fastener includes an elongated shank having a first end, a second end opposite the first end, a cylindrical shank portion having an outer surface, a head located at the first end of the elongated shank, the head including a bearing surface located on the bearing surface of the head, and a threaded portion located at the second end of the elongated shank. The pin member can be fully coated with a coating. A conformable seal element is attached to the pin member, which is adapted to fill the microscopic voids between the bearing surface of the head of the pin member and the surrounding structure under the axial load exerted by the fastener during installation. The seal element can be separate and distinct from the pin member. The seal element can be attached to the pin member for the sake of convenience, but the seal element can deform independently of the pin member and the surrounding structure in response to the forces exerted by the fastener.

摘要： A sleeve interference fastener including a conformable sleeve, wherein the conformable sleeve is comprised of at least one first material having a hardness of X, and a pin member, wherein 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 of an interference fit, at least a portion of the at least one first material of the conformable sleeve conforms to a contour of an inner surface of a hole of a composite structure so as to create a continuous electrical contact at an interface between the inner surface of the hole of the composite structure and the conformable sleeve.

摘要： A locking member for a fastener, such as a nut or a collar, includes a shank portion and a flanged portion, a bore extending the shank portion and the flanged portion and including a first interior portion located within the shank portion and a containment cavity located within the flanged portion, and an inner wall defining the containment cavity. The containment cavity includes an inner diameter that is greater than an inner diameter of the first interior portion of the bore. The inner wall of the containment cavity includes one or a combination of flat/linear surfaces, concave surfaces, and convex surfaces.
