A collated staple strip assembly includes first and second staples, each staple having a bight extending between first and second legs, first and second leg axes, and a bight axis. An attachment strip is secured to at least one of the first and second legs of the first staple and at least one of the first and second legs of the second staple. The attachment strip is deformable about a first axis extending along at least a portion of the height of one of the first and second staples and substantially parallel to the leg axes of one of the first and second staples to position the first and second staples such that the bight axis of the first staple is substantially alignable with the bight axis of the second staple.
