Proto® 3/8" Drive Impact Sockets - 8 Point

Features and benefits

  • Proto® 8 Point Impact Sockets are ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials.
  • The TorquePlus™ design is a high performance drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners.
  • The TorquePlus™ configuration employs a radius-corner design, shifting contact area and stress away from the fastener corners and distributing contact stresses over a large area of the socket, minimizing slippage.
  • The TorquePlus™ internal design minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded, or rusted fasteners.
  • Drive end chamfer and four detents help provide quick positive engagement with drive tool on any of the socket drive walls.
  • Tight tolerances for snug fit on fastener.
  • Large clearance holes, concentric opening and nut end chamfer make it easy to position socket on fasteners.
  • Made from high strength steel to help minimize wall thickness and provide access to fasteners in recesses and where nuts and bolts protrude.
  • Impact sockets are used wherever powered drive tools are used to install or remove fasteners.
  • Impact sockets are designed to withstand higher torque and force associated with impact tools in repetitive application.
  • Socket size stamped on tool for easy identification.
  • Side locking hole.
