10 mm Metric Hex Key fills the 10 mm driver position for metric socket fasteners maintained in crib quantities. The ISO 2936 width band is 10.00 / 9.94 mm, sized just under nominal so the key can enter an in-tolerance socket and bear on the flats.

Tool cribs replenishing loose metric sizes can avoid buying complete sets just to replace one driver. This family supports the metric side of the catalog, including socket-drive cap screws, flat heads, buttons, shoulders, and set screws.

Review the 10 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.
