Proto® Tether-Ready Drive Deep Sockets

SKU 577-5328-TT


  • Manufactured with four detent holes so that the pin detent will engage correctly regardless of the direction the socket is placed on the square drive
  • The Positive Control System requires a separate tool to attach or remove the socket, meaning it cannot be removed without specific intent
  • Chrome finish is applied after the holes are bored for better corrosion resistance
  • 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
