Provided are, among other things, systems, apparatuses, components and methods related to drive pin assemblies. One such assembly includes: a first pin component and a second pin component, each having an engagement end that opens to an interior space and has an angled surface that extends for at least a portion of the width and a portion of the length of such first pin component; and a tightening mechanism at least partially disposed within the interior spaces of the first pin component and the second pin component, for drawing the first pin component and the second pin component closer together, where the angled surface of the first pin component matches the angled surface of the second pin component such that the first pin component and the second pin component slide both vertically and laterally along each other when drawn together.
