A universal jig is compatible with bone plates of varying size, in which different plate sizes having different hole configurations. For example, a longer bone plate may have a first hole pattern along a given length thereof, while various shorter bone plates may have differing hole patterns along respective corresponding lengths. The universal jig includes a combination of hole groupings to provide a jig hole for each hole in the differing hole patterns of the longer and shorter plates, so that the universal jig is useable with a variety of bone plates having disparate hole patterns. For any given bone plate length and hole configuration, a masking cover may be provided to attach to the jig. The masking cover masks off unused jig holes, so that only those jig holes intended for use with a particular bone plate are left exposed.
