MAXFIT ULTRA Torsion Nut Drivers are engineered to withstand the high torque output of an Impact Driver. The Torsion Zone transfers the optimal amount of torque to help prevent stripping and shearing of fasteners. The industrial strength magnet helps to maximize fastener retention, allowing users to complete fastening applications with precision placement. Optimized geometry and recessed corners drive fasteners on the flats, helping to minimize the buildup of metal shavings and reduce rounding of the hex head. Size: 5/16 in
