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.

摘要： A locking member includes a body having a first end, a second end opposite the first end, a bore extending through the body from the first end to the second end, a bearing surface at the first end, fastening means for securing the locking member to a pin member, and a channel formed within the bearing surface and surrounding the bore. The locking member also includes a first insert located within the channel. The first insert is adapted such that, when the locking member is secured against a surface of a workpiece, the first insert prevents passage of a sparking material from within the bore of the locking member.

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.
