Allen wrenches are required to tighten or loosen the fastening hardware supplied with Ruland shaft collars and couplings. They have a ball-end that makes it easier to slide the wrench into the screw. Each key size is color-coded for easy identification and sets come in a plastic carrying case with large labels for organization and quick selection.
