The 1" Double Square 5pc Micro Bitrail is built for work that calls for double square fasteners and quick, repeatable access to the right size. This set includes #1 Double Square x 1", #2 Double Square x 1" in three pieces, and #3 Double Square x 1" on one Micro Bitrail. That gives the set useful depth at the commonly used middle size while still covering the smaller and larger ends of the range. For mechanics, specialty installers, maintenance teams, and anyone who runs into double square hardware often enough to justify a dedicated bitrail, this is a focused and practical solution.
