Made from heat-treated CUSTOM ALLOY76™ steel, it enhanced hardness control and extended bit life. The optimized SHOCK ZONE™ absorbs peak torque to prevent bit breakage, while the chamfered edge maximizes screw-head engagement. Its improved hex geometry reduces stripping, and color-coded bands allow for quick size identification.
