2.5 mm Metric Hex Key supports imported machinery service when the equipment print calls for a single metric driver size. The ISO 2936 width band is 2.50 / 2.46 mm, sized just under nominal so the key can enter an in-tolerance socket and bear on the flats.
Field service carts use individual metric keys for panels, machine covers, and socket hardware on imported systems. This family supports the metric side of the catalog, including socket-drive cap screws, flat heads, buttons, shoulders, and set screws.
Review the 2.5 mm size and ISO 2936 max/min width data against the print before ordering. Keeping the driver as a loose single size helps replace the exact tool without buying a full set. The technical highlights below keep the verified width data separate from general application notes.
