The Bondhus ProHold Ball End screwdriver with ProGuard finish holds the screw tight on the tool every time with its non-magnetic button and super smooth rotational action, with no interference from the ProHold button. The tool strength is not compromised by the button. The ball end inserts into the screw at a 25° angle. The 2 component ComfortGrip ergonomic handle design is slightly textured to help retain grip, even when your hands are wet or oily and features a durable thermoplastic core. Bondhus handles are designed and sized to match the torque capacity of each blade tip. Bondhus professional quality tools are made with Protanium High Torque steel which is 20% stronger, with more torque and twice the wear resistance of standard grades of steel and they provide superior value and offer a lifetime warranty.
