  • Patent number: 5746561
    Abstract: An alignment tolerant fastening system for interconnecting first and second members having first and second bores therethrough, respectively, is disclosed. The fastening system may include a fastening member having a shank portion which is receivable within the bores of the first and second members, a nut member for engaging at least a distal portion of the fastener shank portion proximate the second member, and first and second washers, at least one of which includes a plurality of serrations, positionable within the first bore of the first member, about the shank portion of the fastener. More specifically, for purposes of accommodating a misalignment between the first and second bores, the inner wall of the first washer is slidably engagable with the fastener shank portion and the outer wall of the second washer is slidably engagable or interconnectable with the first bore wall which defines the first bore of the first member.
