The GripEdge Tools 6-pc 3/8” Drive Long Metric Ball Hex Driver Set, No. BHBM6LS, is engineered with GripEdge’s patented Rounding Prevention Technology (R.P.T.). Each bar is formed from S2 steel and precision-machined to reduce thickness and increase access to hard-to-reach areas. The GripEdge patented RPT ball hex geometry enables up to a 22.5-degree pivot angle, further enhancing the increased access to hard-to-reach areas. Each socket features an overall length of 6", perfect for accessing recessed hex screws, as well as large, stamped size markings with black ink fill to increase visibility. Each set comes conveniently packaged into an EVA foam tray.
