The GEARWRENCH combination wrenches are durable, made from alloy steel with a bright, full polish finish. 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 81916 is a 22 piece 12 point, metric long pattern set including sizes 6 mm to 32 mm. The set comes in a sturdy tool roll for storage and organization.
