6 mm Metric Hex Key is selected when a maintenance cart needs an individual metric driver for repeat service work. The ISO 2936 width band is 6.00 / 5.95 mm, sized just under nominal so the key can enter an in-tolerance socket and bear on the flats.
Assembly benches running metric prints use single-size keys to keep operators aligned with the drawing. This family supports the metric side of the catalog, including socket-drive cap screws, flat heads, buttons, shoulders, and set screws.
Review the 6 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.
