1.5 mm Metric Hex Key is a loose metric hex key for socket-drive work where the exact 1.5 mm width is called out on the print. The ISO 2936 width band is 1.50 / 1.48 mm, sized just under nominal so the key can enter an in-tolerance socket and bear on the flats.
Metric machinery maintenance benefits from loose replacement keys because a single lost driver can stall the repair. This family supports the metric side of the catalog, including socket-drive cap screws, flat heads, buttons, shoulders, and set screws.
Review the 1.5 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.
