Size stamped on both sides and on head. They are made from alloy steel with either a full polish or satin finish that resists rust & corrosion. 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 beam for quick, easy, & permanent identification. The box end is offset 15° for increased access to fasteners.
