Product details:

The off-corner loading design on both ends provides a stronger grip on fasteners, reduces fastener rounding, and delivers up to 25% more torque to the fasteners. Sizes are stamped on the open end head, as well as the beam for quick and easy identification. The box end is offset 15 for increased access to fasteners. The 81904 is a 10 piece 12 point, metric stubby length set including 10 mm to 19 mm sizes. The set comes in a blow molded tray for storage and organization.
