Closed end ridged neck threaded fastener

A fastener assembly for securing a first structural component to at least one other structural component, said assembly comprising:

• a first fastener member adapted to be inserted into said first structural component, said first fastener member including a head portion, a generally cylindrical shank portion extending from said head portion;
• a second fastener member including a head portion and a shank portion extending from said head portion;
• threaded means, disposed on said shank portions of said first and second fastener members, for facilitating secure engagement of said first fastener member with said second fastener member;
• and
• anti-rotation means, disposed on an outer surface of said shank portion of said first fastener member, for preventing rotational movement of said first fastener member with respect to said first structural component, while permitting non-destructive axial removal of said first fastener member from said first structural component, said anti-rotation means including a plurality of longitudinal ridges having a constant height along their entire length, said longitudinal ridges being contiguous with one embodiment such that no portion of said outer surface of said shank portion is exposed between any two of said longitudinal ridges.

A fastener assembly comprising:

• a first fastener member including a head portion, a generally cylindrical shank portion extending from said head portion, said shank portion having a longitudinal axis, a plurality of longitudinal ridges disposed on an outer surface of said shank portion in a direction generally parallel to said longitudinal axis of said shank portion, said longitudinal ridges having a triangular cross-sectional shape and a constant height along their entire length, said longitudinal ridges being contiguous with one another such that no portion of said outer surface of said shank portion is exposed between any two of said longitudinal ridges, and an internally threaded longitudinal blind bore extending into said shank portion;
• a second fastener member including a head portion adapted to receive a means for rotationally driving said second fastener member, an externally threaded shank portion extending from said head portion and adapted to threadingly engage said internally threaded bore of said first fastener member, said externally threaded shank portion having threads disposed along an entire length thereof;
• and
• a locking material applied to at least one surface of said fastener assembly, said at least one surface being selected from a group consisting of said threaded shank of said second member, said head portion of said first fastener member, and said head portion of said second fastener member.
